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

Article abstract of DOI:10.1016/j.tet.2006.03.023

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 phenylsulfonylvinyl sulfides, which hav
