1-benzazepin-2-one ring system is an important structural feature of marketed drugs, clinical candidates, and other bioactive molecules. We have developed a new benzazepinone synthesis that employs ring-closingolefinmetathesis as a key step. This route provides efficient access to substituted benzazepinones that are difficult to synthesize via existing procedures.
