A novel Fe-catalyzed hydroalkylation of olefins with para-quinone methides (p-QMs) for accessing phenols has been developed. In this protocol, various olefins could convert to alkyl radicals and undergo addition to para-quinone methides toward C-C bond formation and aromatization. The reaction conditions are mild and the substrate scopes are broad.
A Rh(iii)-catalyzed C-H activation/cyclization of oximes and alkenes for facile and regioselective access to isoquinolines has been developed. This protocol features mild reaction conditions and easily accessible starting materials, and has been applied to the concise synthesis of moxaverine. A kinetic isotope effect study was conducted and a plausible mechanism was proposed.
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.
