Abstract

One-Pot Synthesis of 1-Alkyl-4,5-dihydro-6H-pyrrolo[1,2-a][1,4]benzodiazepin--6-one. -The proposed mechanism involves opening of the furan ring to form an 1,4-diketone followed by reduction of the nitro group and subsequent intramolecular cyclization to the pyrrolodiazepine system. -(STROGANOVA*, T.
