A novel direct transformation of O-glycoside into glycosyl bromide by using trimethylsilyl bromide and zinc bromide has been developed. Treatment of various glycosides (3a-5a, 10, 12 and 14) with trimethylsilyl bromide and zinc bromide in dichloromethane afforded the glycosyl bromides (6, 11, 13 and 15) in 53, 85, 94, 47, 41 and 40% yields, respectively.
