Click inspired synthesis of antileishmanial triazolyl O-benzylquercetin glycoconjugates

摘要

The 1,3-dipolar cycloaddition of deoxy-azido sugars 1 with O-benzylquercetin alkynes (5-7) to afford regioselective triazole-linked O-benzylquercetin glycoconjugates (8-10) was investigated in the presence of CuI/DIPEA in dichloromethane. All the developed glycoconjugates (8-10) were evaluated for anti-leishmanial activity against the promastigotes and amastigotes of Leishmania donovani.
