A rapid, one-pot synthesis of eight benzo[]furo[2,3-]phenazine derivatives has been achieved in moderate to good yields in good yields a multi-component of 2-hydroxynaphthalene-1,4-dione, arylglyoxal, indole (H, CH) in the presence of HPWO@FeO-ZnO magnetic core-shell nanoparticles (MCNPs) under solvent-free conditions using microwave irradiation. The catalyst was synthesised and characterised by X-ray diffraction, EDX, TEM, FESEM, TGA, VSM and atomic force microscope. As an application for the synthesised nanocatalyst, degradation of methylene blue as heavy-mass organic pollution was measured.

Introduction: This study describes a successful approach for the synthesis of 2-(4-bromophenyl)-1-(1H-indol-3- yl) benzo[a]furo[2,3-c] phenazine in the presence of TiO-SOH-catalyst using microwave irradiation.
Objectives: In this paper, we report an efficient and convenient method for the synthesis of phenazine derivatives from benzo[a]phenazin-5-ol, arylglyoxal derivatives, and indoles in the presence of TiO-SOH-catalyst under microwave irradiation.
