A novel glycosidation method has been developed which utilizes a trimethylsilyl halide-zinc triflate catalyst system to activate various benzyl-protected fucosyl, glucosyl and galactosyl esters. The promoter system was extended to use benzyl-protected alkyl glycosides and N-2, 2, 2, -trichloroethoxycarbonyl-protected glucosaminyl and galactosaminyl acetates as glycosyl donors.
