Highly Diastereoselective and Enantioselective Synthesis of α‐Hydroxy β‐Amino Acid Derivatives: Lewis Base Catalyzed Hydrosilylation of α‐Acetoxy β‐Enamino Esters

Abstract

By design: A series of α-acetoxy-β-enamino esters 1 were synthesized and then subjected to catalytic asymmetric hydrosilylation. In the presence of a chiral Lewis base catalyst, the reactions proceeded smoothly to provide a wide range of chiral α-acetoxy β-amino acid derivatives in high yields with good diastereoselectivities and enantioselectivities.
