Synthesis of polyfunctional pyridazine derivatives using a solvent-free microwave assisted method

The synthesis of several polyfunctional pyridazine derivatives has been carried out very efficiently under microwave irradiation and solvent-free conditions allowing short reaction times and high yields. Non thermal effects induced by microwave were obser

Studies on polyfunctionalised heteroaromatics: Synthesis of several new cinnoline and pyrido[3,4-c]pyridazine derivatives

One-pot reaction of ethyl 2-aryhydrazono-3-oxobutyrates with cyanoacetamide afforded pyridazine and pyridine derivatives, which were found to be excellent precursors for the synthesis of different cinnolines and pyrido[3,4-c]pyridazines, respectively.
