Abstract:Synthesis and biological evaluations of a series of 2‐oxonicotinonitriles (2‐ONNs) derivatives are described. Incorporation of branching and solubilizing groups to the 2‐ONN derivative 7 was attained by coupling with several organo‐halides/alkylating agents including three glycosyl bromides under basic conditions. Coupling of 2‐ONNs occurred mainly at the ring nitrogen position and to a lesser extent at the 2‐oxo position giving the O‐alkylated products. Alkylated ONNs and free nucleosides/glycosides derived f… Show more
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.
