A dual-catalysis/anion-binding approach with a chiral hydrogen bonding (HB) catalyst and an achiral nucleophilic cocatalyst was applied to the kinetic resolution of amines. Out of a structurally diverse collection of 22 nucleophilic species, 4-di-n-propylaminopyridine emerged as the most efficient cocatalyst, allowing for the kinetic resolution of benzylic amines with s-factors of up to 67.
