摘要：

The reaction of triphenylphosphine with the o-acyloxy-5 and o-acylamino-azidocinnamates 9, prepared from salicylaldehyde and o-aminobenzaldehyde, results in ring closure to give the 1,3-benzoxazepines 7 and 1,3-benzodiazepines 12, via the intramolecular aza-Wittig reaction of the iminophosphoranes 6 and 10 initially formed, respectively.
