Glycosylative transcarbamylation: efficient transformation of tert-butyl carbamates to novel glycoconjugates

A wide variety of tert-butyl carbamates are converted to the corresponding 2-deoxy-2-glucosaminyl carbamates in a good yield using an N-trichloroethoxycarbonyl-glucosaminyl trichloroacetimidate donor and trimethylsilyl triflate.
