Аннотация

A simple and general synthesis of a series of quinoline-based isoindolin-1-ones, namely N-substituted 7-bromo-2,3-dihydro-1H-pyrrolo[3,4-b]quinolin-1-ones through a one-pot reaction of ethyl 6-bromo-2-(chloromethyl)quinoline-3-carboxylate with various amines in refluxing EtOH–AcOH (v/v, 10:1) solvent system was described. A mechanism involving consecutive Williamson-type reaction of the 2-chloromethyl group with amine followed by intramolecular C–N bond cyclization process is proposed.
