The synthesis of a variety of polycyclicquinolines is described. The target molecules were obtained in two steps by an initial reductive cyclization followed by another intramolecular cyclization in the allylamines afforded from either the acetates or allyl bromides of Baylis–Hillmanadducts of 2-nitrobenzaldehydes and acrylonitrile. The two steps proceeded in one-pot for those substrates in which

A facile synthesis of tri and tetracyclic frameworks containing [1,8]naphthyridin-2-one skeleton from the Baylis–Hillman alcohols via the Johnson–Claisen rearrangement, followed by the treatment with Fe/AcOH in simple one-pot multi-step process is described.
