A series of novel highly functionalized benzoylaminocarbothioyl pyrrolidines were prepared by the reaction of benzoylisothiocyanate with substitueted pyrrolidine derived from α -aminoasit ester via metal catalsed imine -azomethine ylides-l,3-Dipolar Cycloaddition in excellent yield. An example of chiral version benzoylaminocarbothioyl pyrrolidine were also reported. The chirality oryginated from menthyl acrylate as chiral dipolarophile in the cycloaddition cascade and induced three novell chiral centres.Introduction:
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.
