Lewis Base Catalyzed Asymmetric Hydrosilylation of α-Substituted β-Enamino Esters: Facile Access to Enantioenriched β2-Amino Esters via Dynamic Kinetic Resolution

A chiral Lewis base organocatalyzed asymmetric hydrosilylation of alpha-substituted beta-enamino esters is presented. The reactions proceeded through dynamic kinetic resolution to afford various enantioenriched beta(2)-amino esters with high yields (up to 98%) in moderate enantioselectivities (up to 77% ee).
