  Vinyl bis-sulfone methodology in thiosugars: selective access to chiral thiovinyl sulfones and PSE oxathianes

  摘要：

  Based on the vinyl biS-sulfone methodology previously developed to synthesize PSE acetals, an original approach to homochiral carbohydrate-derived PSE 1,3-oxathianes is described. The ready formation of intermediate phenylsul fonyl vinyl sulfides, which have a synthetic potential of their own, emphasizes the versatility of the method. (c) 2006 Elsevier Ltd.

• Expeditious synthesis of β-cycloacetalic sulfoxides. Introducing 1-phenylsulfinyl-2-phenylsulfanylethylene (SOSE), a promising new alkenylsulfur reagent

  日期：2005.2

  In similarity with the strongly electrophilic BPSEs and despite its more electron-rich character, 1-phenylsulfinyl-2-phenylsulfanylethylene (SOSE) reacts with nucleophiles with displacement of the phenylthio moiety. Specifically it reacts with diols under basic conditions to produce beta-cycloacetalic sulfoxides. The reaction has been amply developed in carbohydrate chemistry. (C) 2004 Elsevier Ltd.

  日期：2003.7

  The reaction of hydroxylated thiols with 1,2-bis-phenylsulfonylethylene was investigated: in contrast with diols, a more complex reaction was observed and application to carbohydrate-derived PSE oxathianes was envisaged. (C) 2003 Elsevier Ltd. All rights reserved.
