A catalytic asymmetric conjugateadditionreaction of organocopper reagents, generated from copper salt, a chiral phosphine, and Grignard reagent, with cyclohexenone is highly dependent on the counter anion of copper species, solvents, Grignard reagents, and the structure of the chiral phosphine. The reaction using the combination of 8 mol% of copper iodide, 32 mol% of the amidophosphine 3, and 1.2
