Base‐Catalyzed Intramolecular Self‐Cyclization of o‐Alkenylaryl Isocyanides: Access to 4‐Cyano‐3‐arylquinolines

Abstract 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.
