A chiral bis(sulfonamide)-diamine ligand coordinated with Cu(I), catalyzes the enantioselective Henry reaction with excellent enantioselectivity. Moreover, with the assistance of pyridine, the system promotes the diastereoselective Henry reaction with various aldehyde substrates and gives the corresponding syn-selective adducts.
