A convenient synthesis of S-glycosyl donors of D-glucose and O-glycosylations involving the new reagent

Article abstract of DOI:10.1248/cpb.38.636

The synthesis of S-glycosyl donors from 2,3,4,6-tetra-O-benzyl-α-D-glucopyranose (1) using S,S'-bis(1-phenyl-1H-tetrazol-5-yl) dithiocarbonate (2) was carried out by a one-step reaction. One of the S-glycosyl donors, S-1-(1'-phenyl-1H-tetrazolyl) 2,3,4,6-tetra-O-benzyl-β-D-glucopyranose (3a), was utilized for glycosylation of glycosyl acceptors such as methanol or cholesterol using silver triflate as a promoter.
