Abstract: The 1,2,3-triazole and 1H-1,2,3-benzotriazole-substituted 6,7-dihydroindolizin-8(5H)-one derivatives were synthesized by the reaction of (E)-7-(arylmethylidene)-6,7-dihydroindolizin-8(5H)-ones with 1,2,3-triazole and 1H-1,2,3-benzotriazole in the presence of Selectfluor in moderate yield. The structures of all the products were characterized thoroughly by… read more here.
