A copper(I)−chiral secondarydiamine (L-e) complexcatalyzes an enantioselective conjugate boration of β,β-disubstituted enones in high yields and up to 99% ee. Product chiral tertiary organoboronates can be converted to enantiomerically enriched cross-aldol products between ketones without any racemization.
