Abstract
Attempts to extend Bischler-Napieralski reactions of oxamide derivatives to seven-membered ring analogues of 1,1'-bi-isoquinolinyl were problematic and although a 1,1'-bi-benzazepine was obtained in a low yield an imidazolidinone was isolated in high yield as a result of the capture of acetonitrile by a reactive intermediate.
