In the presence of a chiral iridium complex, commercially available 3-chloro-2-chloromethyl-1-propene (1) was selectively activated for various reductive couplings.

Summary

[edit]
Description
English: In the presence of a chiral iridium complex, commercially available 3-chloro-2-chloromethyl-1-propene (1) was selectively activated for various reductive couplings. Depending on the reaction conditions it allows a selective mono- or bidirectional condensation with one or two external aldehydes with excellent enantiocontrol (>90% ee). This approach occurring simply under mild conditions and avoiding premetalated reagents constructs rapidly chiral homoallylic alcohols, key precursors of important molecular fragments such as furans, pyrans, ketodiols, or 1,3,5-polyols.

[edit]
Public domain
This work is in the public domain in France for one of the following reasons:
  • Its author (or the last of its authors in the case of a collaboration work) died more than 70 years ago (CPI art. L123-1) and did not benefit from any copyright extension (CPI art. L123-8, L123-9 and L123-10)[1];
  • It is an anonymous or pseudonymous work (the identity of the author has never been disclosed) or a collective work[2] and more than 70 years have passed since its publication (CPI art. L123-3);
  • It is the recording of an audiovisual or musical work already in the public domain, and more than 50 years have passed since the performance or the recording (CPI art. L211-4).
Please note that moral rights still apply when the work is in the public domain. They encompass, among others, the right to the respect of the author's name, quality and work (CPI art. L121-1). Attribution therefore remains mandatory.
  1. ↑ Copyright extensions must be considered only in the case of musical works and of authors Mort pour la France (died during conflict, in the service of France). In other cases, they are included in the 70 years post mortem auctoris length (see this statement of the Cour de Cassation).
  2. ↑ The collective work status is quite restrictive, please make sure that it is actually established.
