A highly atom economic one pot synthesis of tetrahydropyridines was achieved by L-proline/TFA catalysed multicomponent reaction of beta-keto-esters, aromatic aldehydes and anilines. The synthesized compounds were screened against Plasmodium falciparum in vitro and one of them showed antimalarial activity with MIC as low as 0.09 mu g/mL. (C) 2008 Elsevier Ltd.

NO2-Fe(III)PcCl@C -catalyzed one-pot synthesis of tetrahydropyridine derivatives
efficient, one-pot synthesis of functionalized tetrahydropyridines by multicomponent condensation of ethyl acetoacetate, two equivalents of aromaticaldehyde, and aromatic amine in the presence of a catalytic amount of NO2-Fe(III)PcCl@C is reported. In this way, a series of pharmacologically interesting substitutedpyridine derivatives were obtained in moderate to good yields.
