摘要
The AuCl3-catalyzed benzannulation of pyridine-containing oxo-alkynes with external as well as internal alkynes proceeds under mild conditions, and a variety of quinoline and isoquinoline derivatives are produced in good to excellent yields. The reaction proceeds through the formation of aza-isobenzopyrylium auric ate complexes as evident from trapping experiments.
