Phase transfer catalysis (PTC) has been used for the synthesis of anomeric
glycosyl derivatives, which included O-, S-, Se- and C- glycosides. These v
arious glycosyl derivatives have been stereospecifically obtained from glyc
osyl halides 1, 2, 3, 14, 26. These reactions proceeded in generally good y
ields,;md were essentially complete within 3 h. (C) 2000 Elsevier Science B
