✦ Synopsis
Conjugate Addition Reactions of Configurationally Stable Benzylic and Allylic Organolithium Species.
-The organolithium species generated from the amines (I) and (IV), BuLi, and (-)-sparteine react with double activated olefins and nitro olefins to provide addition products in good yields with high enantioselectivity at both termini of the newly formed bond.
