A series of β-hydroxy sulfones were synthesized with high enantioselectivities via a new enantioselective ruthenium-catalyzed hydrogenation using MeO-BIPHEP as a ligand. Some β-hydroxy sulfones were used in the synthesis of optically active butenolides and γ-butyrolactones with high yields and enantioselectivities over 95%.

Reduction of 1-chloro-3-phenylsulfonyl-2-propanone with baker's yeast, followed by epoxidation and alkylation with Grignard reagents, yields enantiomerically pure (2S)-2-phenylsulfonyl-2-alkanols, which are converted into (4S)-2-alken-4-olides in 100perce

Enantiomerically pure (2S)-1-phenylsulphonylalkan-2-ols have been prepared from 1-chloro-3-phenylsulphonylpropan-2-one (2) by the folloving successive procedures: reduction with baker's yeast, epoxidation with silver(I) oxide, and alkylation with
Reactions of (2S)-1-Arenesulfonyl-2-alkanol Dianions with Aldehydes. Application to the Synthesis of Enantiomerically Pure (3S)-1-Alken-3-ols and (2E,4S)-4-hydroxy-2-alkenenitriles

, p. 829 - 832 (2007/10/02)
Enantiomerically pure (2S)-1-arenesulfonyl-2-alkanols (1) were prepared by yeast reduction of 1-arenesulfonyl-3-chloro-2-propanones, followed by epoxydation and alkylation.Reaction of dianions of 1 with aldehydes occurred at the pro(R) position of C(1) to give 1,3-diols, which were converted to (3S)-1-alken-3-ols or (2E,4S)-4-hydroxy-2-alkenenitriles in 100percent e.e.
