title: Use of DNA and click chemistries to synthesize combinatorial libraries of galactosyl-phosphodiester clusters.
abstract: Phosphotriester polyalkyne scaffolds bearing two to four alkynes were synthesized by DNA phosphoramidite chemistry. Then two galactosyl azide derivatives exhibiting different linkers were conjugated thanks to a Copper catalyzed Alkyne Azide 1,3-dipolar cycloaddition (CuAAC) "click reaction". This reaction was performed on solid support assisted by microwaves. Thus, small libraries of 4, 8 and 16 galactosyl-clusters were obtained.
