Abstract

The conversion of methyl carbamate to the corresponding free amine is described for a series of 2-amino-2-deoxy-d-glucosamine derivatives. Cleavage of methoxycarbonyl moiety with MeSiCl3 and triethylamine in dry THF at 60° C and subsequent aqueous hydrolysis yields the free amine in 54 to 93% yields. The selective cleavage of methyl carbamates with MeSiCl3 in the presence of a 2, 2, 2-trichloroethoxycarbonyl group or 2-azido glycosides ...
