title: Combinatorial and automated synthesis of phosphodiester galactosyl cluster on solid support by click chemistry assisted by microwaves.
abstract: Small libraries of di-, tri-, and tetragalactosyl clusters were efficiently synthesized using combinatorial methodology, on solid support, by click chemistry assisted by microwaves, starting from different poly alkyne DNA-based scaffolds and two galactosyl azide derivatives. The scaffold was synthesized by standard DNA solid-supported phosphoramidite chemistry using a novel alkyne phosphoramidite and an alkyne solid support. The proportion of each glycocluster in a library was modulated using different molar ratios of both galactose azides.
