Chiral α-substituted carbonyls and alcohols from the S(N)2' displacement of cuprates on chiral carbonates: An alternative to the alkylation of chiral enolates

A highly stereoselective sequence of reactions, based on the anti-selective S(N)2' addition of cuprates to allylic carbonates, transforms alkynes or alkenyl halides into carbonyls having α-chiral centers. The method, which uses menthone as a chiral auxiliary, is a useful alternative to the alkylation of chiral enolates with the added advantage of allowing for the 'alkylation' of sec- and tert-alkyl and aryl groups.

STEREOCHEMISTRY OF THE SN2' DISPLACEMENT OF CHIRAL 1,3-DISUBSTITUTED BROMOALLENES TO FORM CHIRAL ACETYLENES

Optically active 1,3-disubstituted bromoallenes react with a variety of cuprate reagents preferentially is an SN2' fashion with very high anti selectivity.
