Access to 1,3‐Dinitriles by Enantioselective Auto‐tandem Catalysis: Merging Allylic Cyanation with Asymmetric Hydrocyanation

Abstract

Abstract Enantioselective auto‐tandem catalysis represents a challenging yet highlight attractive topic in the field of asymmetric catalysis. In this context, we describe a dual catalytic cycle that merges allylic cyanation and asymmetric hydrocyanation. The one‐pot conversion of a broad array of allylic alcohols into their corresponding 1,3‐dinitriles proceeds in good yield with high enantioselectivity. The products are densely functionalized and can be easily transformed to chiral diamines, dinitriles, diesters, and piperidines. Mechanistic studies clearly support a novel sequential cyanation/hydrocyanation pathway.
