The copper-catalyzed asym. allylic alkylation (AAA) is of great interest in organic synthesis. This reaction was extensively studied using a broad range of substrates, ligands and organometallic reagents. However, the use of racemic substrates was still limited. Although some processes of kinetic resolution are reported in the literature, no examples of quant. deracemization are described as is the case for the Pd-catalyzed allylic alkylation. The development and results of the copper-catalyzed AAA is reported. High enantioselectivities, scope of the reaction and mechanistic considerations are reported herein.
