A highly diastereo-and enantioselective copper(I)-catalyzed henry reaction using a bis(sulfonamide)-diamine ligand

A series of bis(sulfonamide)-diamine (BSDA) ligands were synthesized from commercially available chiral α-amino alcohols and diamines. The chiral BSDA ligand 3a, coordinated with Cu(I), catalyzes the enantioselective Henry reaction with excellent enantios

A highly effective bis(Sulfonamide)-diamine ligand: A unique chiral skeleton for the enantioselective Cu-catalyzed Henry reaction

(Figure Presented) A skeleton in the closet! As a unique chiral skeleton, the newly developed bis(sulfonamide)-diamine, which contains both diamine and bis(sulfonamide) moieties, was a highly effective ligand for the asymmetric Cu(OAc)2-catalyz
