Silver-catalyzed synthesis of pyrrolopiperazine fused with oxazine/imidazole via a domino approach: evaluation of anti-cancer activity

Silver-catalyzed domino synthesis of pyrrolopiperazine fused with oxazine/imidazole by the reaction of pyrrole-derived δ-alkynyl aldehydes and nucleophilic amines was performed. This domino strategy involves the formation of two new C–N bonds and one C–O/C–N bond, resulting in the formation of two new interesting fused heterocycles. Some of the synthesized compounds exhibit promising growth inhibitory activity against leukemia and breast cancer cell lines.
