13C N.rn.r. contacts shifts induced by the addition of the di-t-butyl nitroxide radical have been observed for various aprotic molecules and are shown to be useful as a sensitive probe for detecting the weakly acidic or the active site
The development of efficient synthetic methods of 7-azaindoles has been desired due to the useful biological activities and physical properties. We report the first example of the iridium-catalyzed C3-selective asymmetric...
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.
