The trityl tetrakis(pentafluorophenyl)borate [TrB(C6F5)4] catalyzed stereoselective synthesis of various disaccharides was successfully carried out by treating a new 2-O-acyl-protected glycosyl donor, 3,4,6-tri-O-benzyl-2-O-p-toluoyl-β-D-glucopyranosyl phenylcarbonate, with several glycosyl acceptors, thioglycosides, affording the corresponding disaccharides in high yields.
三苯基四氟苯酯 [TrB(C6F5)4] 催化的各种二糖的立体选择性合成成功地通过处理一种新的 2-O-酰基保护的糖苷供体 3,4,6-三-O-苄基-2-O-对甲苯酰基-β-D-葡萄糖噻吩碳酸酯与几种糖苷接受体硫糖苷进行,实现了高产率的相应二糖的合成。
