Ketones were transformed to chiral acetates by a one-pot process using a lipase and an achiral ruthenium complex under 1 atm of hydrogen gas in ethyl acetate. The same catalyst system was also effective for an asymmetric transformation of enol acetates to acetates under hydrogen without additional acyl donors.
