Abstract
A catalytic and stereoselective glycosylation of various glycosyl accepters with disarmed glycosyl fluorides having phthaloyl or dichlorophthaloyl pro tected amino function is successfully carried out by using a combination of stannic chloride (SnCl4) and silver tetrakis(pentafluorophenyl)borate [AgB (C6F5)(4)] in the coexistence of MS 5A, and the corresponding 1,2-trans dis accharides are obtained in high yields.
