linear and dendritic architectures are described. This synthetic method relies on the coupling of peracetylated azidoglycosyl isothiocyanates and fully unprotected amine-functionalised growing oligomers. Deacetylation of the hemiacetylated thiourea adduct and reduction of the azido groups allow entry into a new coupling cycle. The procedure is quite general, should be easily extended to molecular diversity-oriented
