The synthesis of S-glycosyl donors from 2, 3, 4, 6-tetra-O-benzyl-α-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.
利用 S, S'-bis(1-phenyl-1H-tetrazol-5-yl) dithiocarbonate (2),通过一步反应从 2, 3, 4, 6-四-O-苄基-α-吡喃葡萄糖 (1) 合成 S-糖基供体。其中一种 S-糖基供体 S-1-(1'-苯基-1H-四唑基)2,3,4,6-四-O-苄基-β-D-吡喃葡萄糖(3a)被用于以三酸银作为促进剂对甲醇或胆固醇等糖基化受体进行糖基化。
