  摘要：

  alpha-Oxolactam enamines, namely, 3-piperidino-5,6-dihydropyridin-2(1H)-one (1a) and 3-piperidino-1,5,6,7-tetrahvdroazepin-2-one (1b), were introduced for the first time into the Nenitzescu reaction. The processes yield cyclic adducts 3a-e, 6. On heating in acetic acid, they are transformed into benzofuropyridone 7 and benzofuroazepinones 10a,d, and 12 and, unexpectedly, into chromenopyrrole 8 and chromenopyridines 9a-d and 11.
