oxides.13 This approach can also explain the conversion14 of Z allylic derivatives into olefins with predominant E configuration by a displacement with LiCuMe2. The nature of the leaving group should be decisive in determining which mechanism will be operative: ion pairs should be easily formed from common allylic esters compared with the corresponding lithium carbamates in the presence of copper reagents acting as Lewis acids.15This hypothesis is now under investigation, while evaluation of the scope and limits of the carbamate method is continuing in the case of substituted, noncyclic allylic 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.
