Enantioselective synthesis of 4-substituted 4,5-dihydro-1H-[1,5]benzodiazepin-2(3H)-ones has been accomplished through chiral Lewis base-catalyzed hydrosilylation. The corresponding products were obtained in excellent yields (up to 99%) and enantioselectivities (up to 98%). The absolute configuration of product 3n has been determined as S by X-ray crystallographic analysis.
