Abstract
A novel and facile synthetic protocol for the construction of benzazepine and benzoxepine derivatives through a copper(I)-catalyzed reaction of 2-(2-ethynylphenyl)-1-tosylaziridine or 2-(2-ethynylphenyl)oxirane with sulfonyl azides is disclosed. A ketenimine is the key intermediate during the reaction process.
