ABSTRACTThe syntheses of five propargylated dendrimer scaffolds ranging from 2, 3, 4, 6, and 12 surface groups are described together with a 2-azidoethyl α-D-mannopyranoside. The former is appended to the core structure using highly efficient copper-catalysed azide-alkyne cycloaddition (CuAAC) (“click reaction”) to provide glycodendrimers in an accelerated approach. Two of the core structures are based on cyclotrisphosphazene, thus expanding the scope of the “onion-peel” strategy to build dendritic architectures with a large number of surface groups at the G1 generation only.
