  摘要：

  Condensation reaction of 1H-[1]benzazepine-2,5(3H,4H)-dione (1) with the aromatic aldehydes (2a-e) in the presence of piperidine furnished 4-benzylidene-1H-[1]benzazepine-2,5(3H,4H)-diones (3a-e), whereas in the presence of potassium hydroxide the 7a,8,15a,15b-tetrahydro-15b-hydroxy-5H-[1]benzazepine[4',5',:4,5]-cyclopenta[1,2-c][1]benzazepine-6,9,15(7H,8aH,14H)-triones (4a-e) were formed. The reaction of 1 with formaldehyde yielded the spiro compound (7) as the product of a Diels-Alder dimerization.
