In this letter, we developed a palladiumcatalyzed procedure for the cyclocarbonylation of propargyl amines. Benzene-1,3,5-triyl triformate (TFBen) has been explored as the CO source and also as the key promotor. Various substituted 2-oxo-dihydropyrroles were produced in a facile manner in good yields (up to 90%).
A palladium-catalyzed carbonylative procedure for the synthesis of 1-aroyl-3-aryl-1,5-dihydro-2H-pyrrol-2-ones from propargyl amines and aryl halides with TFBen as the CO source has been developed.
A palladium-catalyzed double-carbonylative cyclization of propargyl alcohols and aryl triflates has been developed. Various 4-aroyl-furan-2(5H)-one scaffolds were produced in good yields with Cr(CO)6 as the CO source. Control experiments were...
A palladium-catalyzed double carbonylation of propargyl amines and benzyl chlorides employing benzene-1,3,5-triyl triformate (TFBen) as the CO source has been developed. By using this protocol, various 1,5-dihydro-2H-pyrrol-2-ones were produced in good yields.
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.
