Asymmetric Assemblies of 1,3-Dienes, Sulfuric Diamide, and Aldehydes to Access 1,3-Diamines through Relay Amine/Palladium Catalysis

Abstract

A relay catalytic protocol using pyrrolidine and palladium catalysis has been developed for asymmetric synthesis of 1,3-diamine derivatives from 3-substituted 1,3-dienes, sulfuric diamide, and aldehydes. This one-pot, three-component reaction features the advantages of a high atom step economy and operational simplicity, providing an efficient and straightforward access to valuable 1,3-diamines incorporating quaternary and tertiary stereogenic centers with moderate to good enantioselectivity.
