method has been developed to construct highly functionalized N‐bridgehead azepine skeletons, which are of great importance in biological and pharmaceutical industry. The reaction proceeds through a rhodium(II) azavinyl carbene intermediate, which initiated the intramolecular CH functionalization with pyrrolyl and indolyl rings. A variety of azepine derivatives were obtained in moderate to good yields under
