A novel, transition-metal free route leading to imidazo[1,2-a]pyridine derivatives via iodine mediated oxidative coupling between 2-aminopyridine and aromatic terminal alkyne has been demonstrated.
A facile and highly efficient iodine-promoted strategy has been delineated for the synthesis of indolo and pyrrolo [1,2-a]quinoxaline derivatives via oxidative Pictet-Spengler type of amino cyclo-annulation reaction using natural amino...
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.
