title: A novel synthesis of (di)-benzazocinones via an endocyclic N-acyliminium ion cyclisation.
abstract: The triflic acid-mediated endocyclic N-acyliminium ion cyclisation provides a facile synthesis of (di)-benzazocinones. On reduction of the 10-phenyl derivative, an unusually non-polar tertiary alkylamine was obtained.
