A simple and inexpensive methodology is reported for the conversion of imidazo[1,2‐α]pyridines to 3‐halo imidazo[1,2‐α]pyridines via oxidative halogenation using DXDMH (X=Cl, Br and I) paired with dimethyl sulfoxide, which serves as the oxidants as well as cosolvent.
In this work, a variety of α-cyanopyrrolines were efficiently synthesized from alkenes, TMSCN and N,N-disubstituted formamides via molecular iodine-catalyzed tandem reaction under neat and mild conditions. This method applies ambient...
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.
