In this study a new, economical and green method was reported for the synthesis of Ag/CdO/ZnO@MWCNTs nanocomposites (Ag/CdO/ZnO@MWCNTs NCs) as a new heterogeneous catalyst. For confirming the structure of synthesized nanocatalyst, XRD, FESEM, EDX, and TEM analyses were utilized. The Ag/CdO/ZnO@MWCNTs NCs as a high performance catalyst were employed for the preparation of a new family of substituted dihydropyrroloazepines using the one‐pot condensation reactions of isatin, ammonium acetate, α‐haloketones, and activated acetylenic compounds in water at room temperature. Another work in this research is investigation of antioxidant property of some synthesized compounds by diphenyl‐picrylhydrazine (DPPH) radical trapping experiment. Presently, bacteria that are not destroyed with drug have generated many problems in the performance of many transferable disease. For this reason, discovering appropriate and new procedures for the dealing with these pathogens is important, and recent study has focused on the investigation of the antibacterial effects on the prepared compounds.
