摘要
Simplified procedures for the Ir-catalyzed asymmetric allylic alkylation reaction are described that often allow substitution products to be obtained with >= 99% ee. Applications to syntheses of important chiral building blocks, such as the Taniguchi lactone and dimethyl 2-vinylcyclopropane-1,1-dicarboxylate, are presented.
