The development of a metal-free protocol for transformations in organic synthesis offers a significant potential environmental benefit. This article reports the exploration of meglumine, a nontoxic and biodegradable amino sugar, as an organocatalyst for the synthesis of biologically active 1H-dibenzo[b,e][1,4]diazepin-1-ones, highly regioselective benzimidazole derivatives and derivatives of quinoxalines. Operational simplicity, mild reaction conditions, shorter reaction times, and use of green solvents are the highlights of this protocol. The advantage of ultrasonic irradiation has been significantly explored for the synthesis of the aforesaid compounds. Furthermore, the multifaceted use of o-phenylenediamine has also been accentuated in the study.

A simple and efficient method is presented for the synthesis of benzodiazepines through the multicomponent reaction of α-phenylenediamine, various aldehydes and 5,5-dimethylcyclohexane-1,3-dione (dimedone) in the presence of the acidic bis ionic liquid 1,4-diazabicyclo[2.2.2]octanium diacetate under ultrasound irradiation. The ionic liquid used is recoverable and reusable. This procedure is simple and environmentally friendly, and offers easy work-up, mild conditions and excellent yield in a short reaction time. All of the synthesized compounds were characterized by IR, 1H NMR, mass spectrometry and elemental analysis.
