Synthesis of Benzazepinones via Intramolecular Cyclization Involving Ketene Iminium Intermediates

Herein, we describe a very straightforward and metal free method for the synthesis of benzazepinones through an intramolecular cyclization. This involves an ortho‐vinyl‐anilino‐amide as starting material which is converted to a keteniminium intermediate that spontaneously cyclize to form a 7‐membere...
