Abstract: | ABSTRACT A simple, one-pot procedure for the synthesis of novel 3-phenyl-3,4-dihydro-2H-benzoa]1,3] oxazino5,6-c]phenazine derivatives by four-component coupling reaction between benzoa]phenazine-5-ol, formaldehyde and amine in the presence of a catalytic amount ZnO-PTA@Fe3O4/EN-MIL-101(Cr) nanopowder in ethanol at room temperature under stirring condition. ZnO-PTA@Fe3O4/EN-MIL-101(Cr) An inorganic magnetic catalyst was analyzes and described by the XRD, TEM, FESEM, TGA, AFM, VSM and ICP-OES. This study presents simple, efficient, and one-pot multicomponent protocol, which provides several advantages such as short reaction times, high yields, easy working up, chromatography-free technique, catalyst recovery, and reusability are other highlights of this work. |
