The enantioselective copper-catalyzed 1,4-addition of Grignard reagents to a$-unsaturated carbonyl compounds was studied with the following Cu' compounds as catalyst precursor and 1,2 : 5,6-di-0 -isopropylidene-3thio-a -o-glucofuranose (Hsiig) as chiral ligand: CuI, iodo[bis(dibutylsulfide)]copper(I
