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.

The gold-catalyzed reaction of pyrrole and indole oximes having a propargyl group attached to the nitrogen atom was studied. The selective 6-endo-dig mode of cyclization was observed for the terminal alkynes giving rise to the formation of pyrazine N-oxides in the presence of a gold catalyst. However, the reaction with substituted alkyne transferred the oxime functionality intramolecularly from one carbon atom to another via the 7-endo-dig cyclization process. This transformation is unprecedented in the literature and is named an oxime-oxime rearrangement.

The synthesis of the pyrazino[1,2-a]indole nucleus was achieved by intramolecular cyclization of several 2-carbonyl-1-propargylindoles in the presence of ammonia. The reaction conditions were optimized using microwave heating and a pool of catalysts. Cycl
