Abstract
AbstractAryl hydrazines, propiolic acid esters and enals serve as a viable substrate combination for an organocatalytic enantioselective Hantzsch type reaction. The method converts readily available starting materials into important chiral heterocycles with good to excellent yields and enantioselectivities, and has addressed the longstanding scope limitation of the classic Hantzsch reaction in the asymmetric synthesis of 2,6‐unsubstituted hydropyridines. The synthetic utility has been demonstrated by the concise enantioselective synthesis of paroxetine.magnified image
