N-Alkoxy-N-acylnitrenium Ions as Possible Intermediates in Intramolecular Aromatic Substitution: Novel Formation of N-Acyl-3,4-dihydro-1H-2,1-benzoxazines and N-Acyl-4,5-dihydro-1H,3H-2,1-benzoxazepine

N-Halogeno-N-alkoxyamides undergo intramolecular aromatic substitution by thermal- or Lewis acid-catalysed heterolysis of the nitrogen-halogen bond.N-Acyl-N-alkoxynitrenium ions are likely intermediates.N-Chloro-N-methoxybiphenyl-2-carboxamide (4) yields N-methoxyphenanthridone (11) quantitatively with AgBF4, while O-2-phenylethyl-N-chlorobenzohydroxamate (19) is converted in good yield into N-benzoyl-3,4-dihydro-1H-2,1-benzoxazine (21) with AgBF4, AgClO4, HgO, and Hg(OAc)2.N-Acetyl-3,4-dihydro-1H-2,1-bezoxazine (22) is formed similarly.O-3-Phenylpropyl-N-chlorobenzohydroxamate (23) cyclises to N-benzoyl-4,5-dihydro-1H,3H-2,1-benzoxazepine (24) with AgBF4.
