Hydrogenation of butane-2,3-dione with heterogeneous cinchona modified platinum catalysts: a combination of an enantioselective reaction and kinetic resolution
Abstract
(R)-3-Hydroxybutan-2-one was obtained with 85–90% ee albeit in low yield by the Pt/Al2O3 cinchona catalyzed hydrogenation of butane-2,3-dione by a combination of enantioselective hydrogenation and kinetic resolution.
