Abstract: | Two novel tricyclic ring systems derived from 3-benzazepines were synthesized; the first, a 6,7,5-ring, 1H-imidazo5,1-b]3]benzazepine-1,3(2H)-dione was obtained using an unusual Stiles reaction while the second, an analogous 6,7,6-ring, pyrimido6,1-b]3]benzazepine-1,3,4(2H)-trione was prepared with base and oxalyl chloride. |
