| Description |
An environmentally friendly and highly efficient procedure
for the preparation of 2,4-disubstituted quinoline derivatives
has been developed by a simple alkynylation 13cyclization reaction
of 2-aminoaryl ketones with phenylacetylenes in the presence of indium(
III) trifluoromethanesulfonate In(OTf)3 under microwave irradiation
and solvent-free conditions. This catalyst can be recovered
after the reaction and reused efficiently in subsequent runs.
