Abstract

A series of optically active β-aryloxy alcohols and β-arylthiol alcohols were synthesized directly by asymmetric transfer hydrogenation of the corresponding β-carbonyl ethers or β-carbonyl sulfides in excellent yields (up to 99%) and excellent enantioselectivity (up to 100% ee) under mild reaction conditions.
