A robust and stable Ru-Biphosphinobioxazoline catalystsystem is discovered for the highly enantioselective hydrogenation of enones to allylicalcohols. A series of acyclic α,β-unsaturated ketones react well affording the desired products in high yields (up to 98%) and enantioselectivities (up to 98% ee). Simple manipulation process and tolerance of water and air make this catalysis more practical
