We have developed a new method for the synthesis of 2,3-dihydroquinazolin-4(1H)-ones in
good to excellent yields via phosphomolybdic acid (PMA)-catalyzed cyclocondensation of 2-
aminobenzamides with aldehydes or ketones in N,N-dimethylformamide (DMF) at room temperature.
The present method proves to be efficient in terms of short reaction time, high yield, simple workup
and easy purification.
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.
