Abstract
2-Aminoaryl ketones undergo smooth Friedländer condensation/annulation
with α-methyleneketones on the surface of nanoporous aluminosilicate
catalyst to afford the corresponding quinoline derivatives in good
yields with high selectivity due to its high surface area, large
pore volume, and high acidity. The use of highly acidic and reusable
AlKIT-5 catalyst makes the Friedländer annulation simple,
convenient, and practical.
