Abstract
A process for the heterogeneous and enantioselective hydrogenation of prochiral organic &agr;-keto compounds with platinum as the catalyst in the presence of a soluble or immobilized chiral aromatic nitrogen base with at least one basic nitrogen atom adjacent to stereogenic carbon atoms, whereby prochiral &agr;-ketoacetals are hydrogenated to optically active &agr;-hydroxyacetals.
