Single-pot nitroalkene -+ cyanoaldehyde transformation, a-methoxy oxime formation, a-and P-alkylations of P-sulphenylated nitro compound, generation of P-sulphenylated silyl nitronate, and sequential Michael addition and Nef reaction have been accomplished in good to excellent yields.
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.
