Multicomponent synthesis and antimicrobial activity of alkyl 4-arylamino-1,2,6-triaryl-1,2,5,6-tetrahydropyridine-3-carboxylates
摘要:
Reaction of arylamines with aromatic aldehydes and beta-ketoesters in the presence of bismuth nitrate or crystalline iodine as a catalyst afforded to alkyl 4-arylamino-1,2,6-triaryl-1,2,5,6-tetrahydropyridine-3-carboxy-lates. Antimicrobial activity of the obtained compounds was studied.

Abstract A simple, highly versatile, and efficientsynthesis of functionalized piperidines is achieved by four-component cyclo-condensation of aldehydes, aromatic amines, and acetoacetic esters using magnesium hydrogensulfate [Mg(HSO4)2] as a catalyst in acetonitrile as the solvent at roomtemperature. The key advantages of this procedure are high yields, easy work-up, and purification of products

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. All rights reserved.
