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

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

Synthesis of methyl 4-thio-β-cellobioside. A reinvestigation

The best yield for the synthesis of the title compound was obtained by nucleophilic displacement of the di-O-triflyl group in methyl tri-O-benzyl-4-O-triflyl-β-D-galactopyranoside by 2,3,4,6-tetra-O-acetyl-1-S-acetyl-1-thio-β-D-glucopyranose in HMPA in the presence of diethylamine. Under these conditions, the formation of unsaturated side products was decreased.
