First Example of Ring Expansion of Activated Quinolines and Isoquinolines:
Benzoazepines. — Activated quinoline and isoquinoline derivatives (IV) and
11- 164 Novel
(I) undergo unexpected ring expansion by diazocarbonyl compounds (II) via C—C
insertion to produce bicyclic azepines (V) and (III), respectively. The reaction proceeds
in the presence of a catalytic amount of copper triflate and with a high degree of regioselectivity. — (YADAV*, J. S.; REDDY, B. V. S.; GUPTA, M. K.; PRABHAKAR,
