Hello, Nuklear!

Thanks a lot for contributing to the Wikimedia Commons! Here's a tip to make your uploads more useful: Why not add some categories to describe them? This will help more people to find and use them.

Here's how:

1) If you're using the UploadWizard, you can add categories to each file when you describe it. Just click "more options" for the file and add the categories which make sense:

2) You can also pick the file from your list of uploads, edit the file description page, and manually add the category code at the end of the page.

[[Category:Category name]]

For example, if you are uploading a diagram showing the orbits of comets, you add the following code:

[[Category:Astronomical diagrams]]

[[Category:Comets]]

This will make the diagram show up in the categories "Astronomical diagrams" and "Comets".

When picking categories, try to choose a specific category ("Astronomical diagrams") over a generic one ("Illustrations").

Thanks again for your uploads! More information about categorization can be found in Commons:Categories, and don't hesitate to leave a note on the help desk.

Abacavir

Nuklear your synthesis is incorrect, you make the wrong stereoisomer in the final product. In essence you make the 1,2-product, not the 1,4-product. look at the strucures!! ok thanks, i edit to correct mistake. sorry i did that, my mistake. although, dan drew wrong isomer in his book 6 which probably distracted my attention.

Error in Nitroglycerine synthesis figure

Your figure File:Nitroglycerine synthesis.png Shows the molecules containing four carbons. There are only three carbons in these structures. Remove the left most carbon and attach the hydroxyl to the middle carbon - similarly attach the nitroxy group to the product - 1,2,3-Trinitroxypropane (3-carbons).

Wikipedia 'List of cocaine analogues' article images needed

Hello,

I notice you make a lot of molecular structure 2D images. I am currently restricted to a library computer and cannot make images for upload.

I was wondering if you could assist me in my endeavor of adding certain images for inclusion at the Wikipedia 'List of cocaine analogues' page.

What I need is mostly those from Singh's SAR of Cocaine paper (45 pages in on the page finder; pg. 970 or so as enumerated on the paper itself: the chemical structures 183a-(through)-d, 184a & b, 185a-d, 186-188 on 'Scheme 42', on pg. 50 (974) structures 196a-o, 197a-g, 198a-e, 199a & b, 200 & 201a-e ... and more down to page 61 or so; namely N-modified analogs & such.)

Any help making these would be greatly appreciated. Nagelfar (talk) 21:52, 24 February 2015 (UTC)[reply]

Sure, just give me a few days & i'll look into it and try and help you with it.--Nuklear (talk) 11:09, 2 March 2015 (UTC)[reply]

Thanks for the much needed "R=..." images... Hey, I had a question maybe you know the answer to: Is the IUPAC on given on 2'-Acetoxycocaine wrong? It is:

(1R,2R,3S,5S)-Methyl 3-((2-acetoxybenzoyl)oxy)-8-methyl-8-azabicyclo[3.2.1]octane-2-carboxylate

Though using the IUPAC of cocaine as a starting point my assumption would be it is supposed to be:

methyl(1R,2R,3S,5S)-3-(2-acetoxybenzoyloxy)-8-methyl-8-azabicyclo[3.2.1]octane-2-carboxylate

Is the stereoisomerism of this analog different in this case, and if so, would it be in other cases? If not, what is the nature of the orientation of this error and how does it related to the isomers? Nagelfar (talk) 21:03, 3 March 2015 (UTC)[reply]

Ok, I ran both names through CD and I get exactly the same structure in both cases.
So, both names are recognized by CD "convert name to structure" function.--Nuklear (talk) 03:53, 4 March 2015 (UTC)[reply]

The structures through www.chemicalize.org are different in that one has two shaded wedge bonds (between the 2beta position & half the nitrogen bridge) and the other they are solid wedge bonds, not shaded. I thought this had to do with isomerism.

Anyhow, I will continue to revert any "ban reverts" they put on you in the 'list of cocaine analogues' article. There is discussion on my Wikipedia user talk page to the effect that such will be tolerated but that they are considered "my edits" apparently. The images [1] & [2] need to be upgraded, the nitrogen is off and half the bridge is missing, but otherwise thank you! (For aesthetic consistency through the article I'd like the OBz abbreviation to be the fully drawn out benzoyloxy, though, but that's just personal taste.) Nagelfar (talk) 18:45, 4 March 2015 (UTC)[reply]

I changed my mind, I like the OBz abbr. in the boxes ;-) I still need your help with those "R" & "X" images. Nagelfar (talk) 00:54, 10 March 2015 (UTC)[reply]

Thanks alot for your input to try and get done this free work. I'll look into it and try and help you as far as possible.--Nuklear (talk) 04:18, 10 March 2015 (UTC)[reply]

Misplaced N groups

Dear Nuklear, in many of your schemes there is a ChemDraw bug, which misplaces things stacked over a Nitrogen (NMe or NH). (For example see old version of File:Theophylline synthesis 1.svg) Could you please fix this with Inkscape before you upload?--Kopiersperre (talk) 07:39, 5 March 2015 (UTC)[reply]

Your account will be renamed

Hello,

The developer team at Wikimedia is making some changes to how accounts work, as part of our on-going efforts to provide new and better tools for our users like cross-wiki notifications. These changes will mean you have the same account name everywhere. This will let us give you new features that will help you edit and discuss better, and allow more flexible user permissions for tools. One of the side-effects of this is that user accounts will now have to be unique across all 900 Wikimedia wikis. See the announcement for more information.

Unfortunately, your account clashes with another account also called Nuklear. To make sure that both of you can use all Wikimedia projects in future, we have reserved the name Nuklear~commonswiki that only you will have. If you like it, you don't have to do anything. If you do not like it, you can pick out a different name.

Your account will still work as before, and you will be credited for all your edits made so far, but you will have to use the new account name when you log in.

Sorry for the inconvenience.

Yours,

Nuklear; your 'List of phenyltropanes' page:

I'm going to get to all of S. Singh's tables from here and include them but I need some of your input. Should I just title them like in that paper (i.e. 3β-(4′-Substituted Phenyl)tropanes (as sub-cat. of Phenyl ring substituted phenyltropanes) … etc.) or should I go through the classification system you have in place. (i.e. 2-Carboxymethyl esters … β,α Stereochemistry … Tricyclic Tropanes … & et cetera) if it's the latter I'm going to need your help, and if its the former how should I interpolate the tables to be incorporated between your system in place? Or should we work together and just overhaul the whole schema of the article as it now stands for something that can easily incorporate the fifty some pages Singh dedicated to phenyltropanes in that paper along with the RTI research you've already transcluded? Please get back to me, I can also do edits for you if they're constructive and you're otherwise hindered by edit-restrictions due to past policy faux pas. Nagelfar (talk) 20:16, 25 March 2015 (UTC)[reply]

Ok, he got things like meta-substituted I didn't bother about, just add those in if you want to I don't mind either way.--Nuklear (talk) 07:16, 27 March 2015 (UTC)[reply]

What do you mean by meta-substituted? Which ones are those in the paper? (Give me a page number and I'll get them done, or some other way to decipher what you mean by meta-, if you mean substitutions of substitutions I need your input, you're more astute than I, give me the compound numbers (e.g. n-(through)-n) and I'll incorporate their tables). I still need those R-substitution/modification images in my tables at my cocaine analogues list, too. BTW Nagelfar (talk) 23:45, 27 March 2015 (UTC)[reply]

There's a few meta compounds on 933 but only dat is recorded. i included them. if u want to include anymore then be obliged, but i can't be bothered with it anymore it's getting boring now.--Nuklear (talk) 08:09, 28 March 2015 (UTC)[reply]

OK, I understand. I'll get to the 16 & 17s, and any other I see with both an X & Y. If your interest is ever piqued again, throw me a line at which ones need to be included (did you get to the metal chelated ones?) which numbers from Singh's paper, and I'll do it for you. (On page 961 (37th) scheme 32 has ones that have a W, X, Y & Z 6/7 substitution!) Nagelfar (talk) 18:00, 28 March 2015 (UTC)[reply]

Swastika formulas

Hi.

I was slightly shocked finding that Formula in the enwiki article. Are you aware that the swastika is a worldwide known symbol of one of the most cruel criminal political movement in history, and in some countries that sign is also illegal? So, i intervened in enwiki. May i ask if you made more drawings similar to that? --Itu (talk) 07:45, 11 November 2015 (UTC)[reply]

Yes there was one other instance of chemical formulae that could be drawn in a swastika like design. If you take meprobamate which is derived from methyl propyl malonic ester and then to do the diethyl analog. That was the only other example I have come across. This is scientific chemical formulae though rather than artistic drawings.--Nuklear (talk) 17:06, 14 November 2015 (UTC)[reply]

I found another swastika formula in the book I was studying today called Petrichloral.--Nuklear (talk) 11:50, 22 May 2016 (UTC)[reply]

Also for Loprodiol.

Hi Nuklear, from which patent did you take the scheme? It seems that from https://www.google.com/patents/US3700681 but I cannot see there the alkylation step with t-BuBr.

Your "boring to you" List of phenyltropanes

Hey Nuklear, me and user:Edgar181 have done quite a bit of work filling out your List of phenyltropanes WP page, check it out, see if it piques your interest on adding whatever remaining RTI structures we couldn't find. For instance, we couldn't find RTI-262: don't know where your main source was from, but the few omissions and corrections yet to do would be appreciated, you may be bored of it, but for some reason it still holds my interest, hoping all the effort in the interim piques a bit of follow-up interest with the pages original author, at least; At least check out it's current/latest permutation. Nagelfar (talk) 19:48, 10 May 2017 (UTC)[reply]

(In response to yours, on my talk) Good to hear back from you finally, as well, Nuklear: I presume what you mentioned to me is a chemistry-oriented (and not just information) database? Grey-market pharmaceutical synth, how-to's etc.? (I've been thinking of adding Singh's PT synth. schematics to wiki-How-To with inter-wiki links, as a matter of fact, from here on the WP pages. I don't know if you're familiar with bluelight.org, specifically Neuroscience and Pharmacology discussion; there are very connected, intelligent, people there. Pen & paper penpals with established chemists (I know a friend in England, Sean, who writes back and forth with a well known retired chemist; said he could pull some strings ands get my U.S. felonies expunged for a visa for greymarket enterprising; this was years ago the offer came up in conversation) Nagelfar (talk) 19:34, 20 October 2017 (UTC)[reply]

File:Xfiles.png

Hi Nuklear. What is the right title for File:Xfiles.png? Please use {{Rename}} for that, rather than {{Delete}}. Also, I noticed that you've made multiple malformed deletion requests. When you want to delete a file with the {{Delete}} template, you must follow the instructions in the template, including the "Click here to show further instructions" portion. Alternatively, you can click the "Nominate for deletion" link in the left sidebar, under the "tools" section, which does all of the work for you. Please do one of these, otherwise you create a lot of work for other people. If you don't see the "Nominate for deletion" link in the left sidebar, you can use the JavaScript method of enabling AjaxQuickDelete on Special:Preferences#mw-prefsection-gadgets once and then refresh once. — Jeff G. ツ_{please ping or talk to me} 08:44, 9 February 2021 (UTC)[reply]

Droxicam

Your recently-added File:Droxicam synthesis (original).svg has incorrect chemistry. The pyridyl starting material has a PhOCONH- sidechain (see US4563452 example 2a using 2-phenoxycarbonylaminopyridine ), not NHCbz. Please correct this. I am aware that you are currently block evading with an IP to edit en-Wikipedia and I have commented on the Talk Page at en:User talk:2.101.54.127, which, so far, you have ignored. It would be better for all concerned that you engage with me there. I welcome some of your contributions such as the research which goes into your chemical drawings / sources but as you will note from my multiple banreverts, other uncited additions are unwelcome. Michael D. Turnbull (talk) 14:22, 3 July 2024 (UTC)[reply]

It's not incorrect. Look i got the procedure from this website but it is in the patent also:

https://www.chemdrug.com/article/8/3284/16419975.html

They said I can have my account reinstated though a while a go. Do you think you would be able to do this for me? Thanks Nuklear (talk) 14:54, 3 July 2024 (UTC)[reply]

Did you know that Cbz means carboxybenzyl?

In this case, you are the one who is incorrect! Cbz is benzyloxycarbonyl = PhCH2OC(O)- derived from reacting en:benzyl chloroformate with e.g. an amine. As the patent and your link make clear, the compound used was a simple phenyl en:carbamate. You have also made an error on File:Lotrifen synthesis.svg. The cyclisation reaction with NaH gives the en:1,2,4-Triazole directly, whereas you have drawn the heterocycle with an extra hydrogen in the 3-position, which, if you think about it cannot be correct as that carbon atom is always at the oxidation level of a carboxylic acid, not an aldehyde. I am not an admin, so I cannot help you with the reinstatement of your account. Indeed, the more you edit as a en:WP:SOCKPUPPET the less likely it is you will ever be reinstated. Michael D. Turnbull (talk) 15:14, 3 July 2024 (UTC)[reply]

Thanks for helping me out with the typos. All has been corrected now. Also the typo was copied across from the chemdrug page for lotrifen but I respect what you are saying wrt phenylcarbamate and not Cbz group in the other post.

Quinagolide

I noticed that you were adding a synthesis of quinagolide to its article today. The route you described may have been the first one that was used to make it but as you will have realised, it is totally impractical for manufacture of the drug. Novartis published their manufacturing route in doi:10.1021/op0000531 and this would be a much better candidate for inclusion in en:Quinagolide, IMO. That route is also discussed in the 2023 paper doi:10.1039/d3ob00946g which you cited. Maybe you would like to create a suitable drawing for the Novartis route, ready to replace the ones you currently have? Michael D. Turnbull (talk) 15:06, 4 July 2024 (UTC)[reply]

Okay thanks for the tip. I'll see about that tomorrow.

Thanks for doing the new route. In updating the article today, I noticed that there is a minor error. The ChemSpider entry for the intermediate used with the lithiated naphthalene has E geometry. According to ChemSpider, the Z form of that molecule (as you drew) is unknown. Maybe you could fix that when you have a moment? Michael D. Turnbull (talk) 15:56, 7 July 2024 (UTC)[reply]

The Z form is here. Let me check the paper again to see https://pubchem.ncbi.nlm.nih.gov/#query=42466-69-3

The Z form is shown in the article also.--Nuklear (talk) 05:07, 8 July 2024 (UTC)[reply]

OK, thanks for checking that. I don't have access to ACS publications, as they don't provide access via the Wikipedia Library and all my other subscriptions are via the UK. I looked again at ChemSpider and it does have the Z form: I don't know why I missed that! I've updated the article to fix my error.

Another couple of things. I worked on your text/diagram at en:Cefdinir, moving the synthesis section up a bit and removing some of the primary sources when there are better secondary ones. In doing that, I noticed that you drew the protecting group which is removed in the final step as CO₂PMB, which I take as meaning p-MethoxyBenzyl. However, all the references make it clear they actually used a benzhydryl ester CO2CHPh2. Can you fix that? This shows a pitfall of using abbreviations in our chemical drawings and one other that you consistently use is "TM", which I assume you think of as "Target molecule". However, when used in foreign-language Wikipedias, readers are more likely to think of it as the standard "trademark" symbol! For that reason, in my chemical drawings, I usually put the name of the compound (i.e. the article's title) at the end of the final arrow. For example File:Boscalid_synthesis.svg. Also, I use a vertical arrow sometimes when going from compounds in the first row to those below. It's not worth your going back and re-doing your many uploads to alter that but maybe you would think of these ideas for the future? Michael D. Turnbull (talk) 12:20, 8 July 2024 (UTC)[reply]

The PNB group method was copied from page 170 in Lednicer book 6 on organic synthesis. According to copying the smiles from chemdraw into pubchem the abbreviation counts for paranitrobenzoyl protecting group. He left this reference:

Inamoto Y, Chiba T, Kamimura T, Takaya T (June 1988). "FK 482, a new orally active cephalosporin synthesis and biological properties". The Journal of Antibiotics. 41 (6): 828–30. doi:10.7164/antibiotics.41.828. PMID 3255303.

Yes i accept Bzh appears to be the correct choice of protecting group here. But this method in itself is old as I pointed out the Ranbaxy method appears to be the newest (2003). Maybe i'll take another look if I have time.--Nuklear (talk) 14:03, 8 July 2024 (UTC)[reply]

I was reading doi:10.7164/antibiotics.41.1602 where they use the acronym "DPM" which I assume means DiPhenylMethyl. I agree that PNB would be p-nitrobenzyl but you originally had PMB! As I've said previously, I don't like the use of abbreviations that may be confusing to non-chemists, when we can use simple standard formulae like OCHPh2 or even OCH(C6H5)2. anyway, I see you have gone for Bzh, which is OK.
