Abstract
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.
Key words
gold - catalysis - benzannulation - quinolines - isoquinolines

11 Indeed 1a was
found to react exothermally when brought in contact with DMAD in
DCE at a similar concentration.
12 Oxo-alkynes 1a -d were prepared from the corresponding pyridine-2-chloro
aldehydes by Sonogashira coupling; similarly, 1e was
prepared from iodoaldehyde 3 by Sonogashira
coupling.

14 An alkyne with an aryl and an ester
substituent, e.g., PhCºCCO2 Me was found not to react
either with the electron-rich oxo-alkyne 1a or
the electron-deficient oxo-alkyne 1e ; presumably
in this case the HOMO-LUMO energy difference is too high
for both pairs of reactants.
15 This Sonogashira coupling was unsuccessful
(<10%) under the classical conditions [PdCl2 (PPh3 )2 /CuI] using
a variety of bases such as Et3 N, i -Pr2 NH,
K2 CO3 , or NaHCO3 .
