Abstract

The asymmetric conjugate addition of diethyl zinc to cyclohexen-2-one, chalcone and benzalacetone was studied with 0.5% copper (II) triflate and 1% chiral phosphorus ligands derived from TADDOL. Among the several ligand tested, the cyclic phosphite obtained with 1S,2R phenylcyclohexanol gave up to 96% ee of conjugate adduct to cyclohexenone.
