Abstract

Molecular sieve supported lanthanum catalyst proved to be an efficient heterogeneous catalyst for the one-pot, four-component synthesis of polyhydroquinoline derivatives from aromatic aldehydes, dimedone, ethyl acetoacetate and ammonium acetate in ethanol via Hantzsch reaction. The method has several advantages such as simple reaction conditions, short reaction time, high yields and simple workup procedure, which make it an attractive route for the synthesis of polyhydroquinolines. The catalyst could be reused several times without the loss of its initial activity.
