Intermotecular transfer of an alkenyl group in enamines: Application to synthesis of [b]-fused pyridines

A novel intermolecular alkenyl transfer of enamines was developed for the preparation of cycloalkenylaminomethyleneoxazolones, which were thermally cyclized to [b]-fused pyridines in good yields. The functional manipulation of the pyridines provided versatile precursors for further annulation to tricyclic ring systems. Copyright (C) 1996 Elsevier Science Ltd.
