Abstract:A series of 1,3-diphenylpyrazole-chromenoquinolin-6-one compounds were designed and synthesized by
using a greener and recyclable heterogeneous Amberlite IR-120H resin as a catalyst, in the presence of
ethanol reflux conditions. Interestingly, the catalyst can be recovered after completion of the reaction and
can be reused without loss of catalytic property. Therefore, this method provides a green and
environmentally benign much improved protocol for the synthesis of 1,3-diphenylpyrazolechromenoquinolin-6-one … Show more
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.
