Abstract
Vinyl-substituted pyrazo[1,4]-oxazepines were prepared through an intramolecular regioselective cyclization method under gold catalysis. This organic transformation achieved selective C–N bond formation via 7-exo-trig cyclization, resulting in vinyl-containg pyrazolo[1,4]-benzooxazepines and pyrazolo[1,4]-naphthoxazepines in one-pot with moderate to very good yields.
