[reaction: see text] A short-step synthesis of versatile chiral building blocks for triazole antifungal agents such as ZD0870 and Sch45450 was developed via catalyticenantioselective cyanosilylation of electron-deficient ketones as the key step. High enantioselectivity was produced using a catalyst prepared from Gd(HMDS)(3) and ligand 5 in a 2:3 ratio. This new catalyst preparation method was superior
