1,3-Dipolar cycloaddition of the acetylated 1,2-trans- and 1,2-cis-cel
lobiosyl, -lactosyl, -maltosyl, and -melibiosyl azides with various ac
etylenedicarboxylic acid esters gave the corresponding 1-N-glycobiosyl
-1,2,3-triazoles (1a,b,c-8a,b,c) which have been used as glycosyl dono
rs for the synthesis of oligosaccharides (15-17) and an anthracycline
type antibiotic (18).
