A Mn(iii)-catalyzed cascade cyclization of o-acyl aromatic isocyanides with boronic acids was examined to give a series of 3-hydroxyindolenines in single-step. This cascade process involved a transmetalation/nucleophilic addition/intramolecular cyclization sequence.
A ruthenium(II)‐catalyzed hydroamination of allenoates with arylamines has been developed. This strategy provides an approach to synthesize E‐allylic amines in good yields with high atom‐economy and high levels of chemo‐, regio‐ and E‐selectivities with a broad substrate scope.
A novel base-catalyzed intramolecular self-cyclization reaction of o-alkenylaryl isocyanides has been successfully developed. This reaction provides a general, efficient and atom-economic method to access 4-cyano-3-arylquinolines with broad scope of substrates and excellent functional group compatibilities.
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.
