protection of alcohols in the various reaction components. Reaction of N-benzyloxycarbonyl-l-aspartic monothioanhydride with unprotectedglycosyl amines, followed by capture of the thioacid intermediate with N-sulfonyl aminoacid derivatives results in a three-component convergent synthesis of glycosylated peptides.
