An oxidative [3+1+1] convergent domino cyclization is disclosed. This protocol enables to get quinoline, quinoxaline, quinazolin‐4(3H)‐one and benzo[d]thiazole attached 2,4,5‐trisubstituted oxazoles from methyl azaarenes, benzoins, and NH4OAc in the presence of iodine and molecular sieves without any metal catalyst. The reaction features wide substrate scope, good functional group tolerance, mild reaction conditions, and easily available substrates.
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.
