The conformationally restrained dibenzothia(oxa)zepines and dibenzazepines 4-6 analogous to the antidepressant Sintamil were prepared easily by π-cationic cyclization of the N-acyliminium ions 9A-C precursors with neat trifluoroacetic acid in three step-sequence starting from available amines and anhydrides. The regioselectivity in the reduction of imides especially in the maleimide derivatives as well as in the cyclization step was also discussed.
