In this paper , a high‐yielding, atom‐efficient, and green protocol for the synthesis of novel pyrazolo‐fused benzophenazines utilizing a multicomponent condensation reaction between 2‐hydroxynaphthalene‐1,4 ‐dione, o‐phenylenediamine, aromatic aldehydes, and 4‐ methylbenzenesulfonohydrazide in the presence of phosphotungstic acid (H 3 PW 12 O 40 ) under microwave irradiation (MWI) in EtOH is reported. The novel series of 1H‐benzo[a]pyrazolo[3,4‐c]phenazine derivatives may be useful for biological screening tests. More details will be discussed by Dr. Razieh Mohebat and her co‐workers on page 1259‐1265 in this issue.
