Abstract:Certain 2‐amino‐6‐alkoxy‐4‐arylpyridine‐3,5‐dicyanide 1a‐e were prepared via a straightforward process using microwave technology rather than conventional methods. This involved reaction of arylidenemalononitrile thru propanedinitrile in the occurrence of sodium alkoxide under MW. While, their positional isomer 4‐amino‐6‐alkoxy‐2‐arylpyridine‐3,5‐dicyanide 3a‐j have been separated from the reaction of aryl aldehydes with 2‐aminoprop‐1‐ene‐1,1,3‐tricarbonitrile 2 in the presence of sodium alkoxide using microwa… 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.
