Abstract

AbstractA simple, rapid and conceptually new efficient protocol for the synthesis of 4,5‐dihydro‐1H‐benzo[g]indazole derivatives from novel enaminones prepared via Blaise reaction under catalyst free conditions is reported involving polyethylene glycol (PEG‐400) as an efficient recyclable medium without using any organic co‐solvent or additive by Microwave irridation with 91–95 % yields without chromatography.
