Copper reagents derived from imidazoles (I) undergo highly regioselective and stereoselective substitution reaction with optically active substrates (III). The products can be further transformed into imidazolium salts such as (V). The reaction is extended to the synthesis of related 2-pyridyl derivative (VII). -(KOBAYASHI*, Y.; KIYOTSUKA, Y.; SUGIHARA, Y.; WADA, K.; Tetrahedron 71 (2015) 37, 6481-6487, http://dx.
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.
