Microwave-assisted one-step rapid synthesis of dicyano imidazoles by HNO3 as a high efficient promoter

Microwave-activated synthesis is a special and remarkable technique in modern synthetic organic chemistry. In the current research, it described microwave-assisted of 2-aryl-4,5-dicarbonitrile imidazole derivatives via one-step reaction between aromatic aldehydes 2,3-diaminomaleonitrile (DAMN) using HNO3 as metal-free catalyst strong oxidizing agent. The present methodology has significant advantages like synthesis, shorter times, available starting materials, higher yields products with easy purification process, cleaner than previously reported processes. valuable benefits this method have provided promising prospect for easier, greener, faster diciano imidazoles.
