Domino coupling of furan‐2‐yl (phenyl) methanol and 2‐(1H‐pyrrol‐1‐yl) aniline has been achieved in the presence of 10 mol% phosphomolybdic acid in CH3CN under reflux to afford the corresponding biologically active 10‐aryl‐9a,10,12,12a‐tetrahydrobenzo[b]cyclopenta[f]pyrrolo[1,2‐d][1,4]diazepin‐11(9H)‐ones in good yields. Broad substrate scope, short reaction times, environmentally benign, and operational simplicity makes this method more attractive.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
