New multifunctional chiral phosphine (phosphine-amide type) LB8 and BINOL derivative co-catalyzed asymmetric aza-MBH reaction of 5,5-disubstituted cyclopent-2-enones 1 with N-sulfonated imines 2 afforded the corresponding optically active adducts 3 in good to outstanding yields with moderate to good ee's under mild conditions. The steric hindrance environment of BINOL derivatives as well as the nucleophilicity
