Chiral Boro‐Phosphate Catalyzed Asymmetric Transfer Hydrogenation of 1‐Enal Substituted 2‐Naphthols: Access to Axially Chiral Styrene‐Type Allylalcohols

Abstract Herein, we present a chiral boro‐phosphate catalyzed atroposelective asymmetric transfer hydrogenation method, leading to a family of axially chiral styrene‐type allylalcohols. This dynamic kinetic resolution approach portrays simple procedure, mild conditions and good enantiocontrol (51–95% ee), thus providing an important alternative to assemble the challenging atropisomeric aryl‐acyclic alkene scaffolds. magnified image
