Solvent effect on copper-catalyzed azide-alkyne cycloaddition (CuAAC): synthesis of novel triazolyl substituted quinolines as potential anticancer agents

Abstract

A regioselective route to novel mono triazolyl substituted quinolines has been developed via copper-catalyzed azide-alkyne cycloaddition (CuAAC) of 2,4-diazidoquinoline with terminal alkynes in DMF. The reaction provided bis triazolyl substituted quinolines when performed in water in the presence of Et(3)N. A number of the compounds synthesized showed promising anti-proliferative properties when tested in vitro especially against breast cancer cells.
