Abstract
A series of beta-hydroxy sulfones were synthesized with high enantioselecti vities via a new enantioselective ruthenium-catalyzed hydrogenation using M eO-BIPHEP as a ligand. Some beta-hydroxy sulfones were used in the synthesi s of optically active butenolides and gamma-butyrolactones with high yields and enantioselectivities over 95%. (C) 1999 Elsevier Science Ltd.
