Abstract
AbstractThe zinc acetate promoted asymmetric hydrosilylation of various ketones and imines under solvent‐free conditions was examined by using an unprecedented low catalyst loading. Exposure of ketones to 0.05 mol % Zn‐based chiral diamine complex in the presence of triethoxysilane afforded enantioenriched alcohols in excellent yields (up to 98 %) and enantioselectivities (up to 97 % ee). This methodology also allowed for the chemoselective 1,2‐reduction of α,β‐unsaturated ketones and imines.
