Diastereoselective asymmetric allylation of chiral α-keto-amides with allyltrimethylsilane. Preparation of protected homoallylic alcohols
Abstract
In the presence of Lewis acids, protected homoallylic alcohols of high diastereoisomeric excesses (up to 89%) were obtaine by he addition of allyltrimethylsilane to chrial α-keto-amides derived from (S)-proline esters.
