Abstract A simple, inexpensive and efficientone-pot synthesis of piperidine derivatives was achieved in excellent yield via the three-component reaction of substituted aniline, 1,3-dicarbonyl compound and aromatic aldehyde using phenylboronic acid as catalyst.
Fe(NO3)3·9H2O is used as an efficient and effective catalyst for the one‐pot three‐component synthesis of highlyfunctionalizedpiperidines from aromatic aldehydes, anilines and b–ketoesters in ethanol at ambient temperature. This procedure includes some important aspects like the easy work‐up, no need to column chromatography, simple and readily available precursors, and good to high yields.
Photocatalytic activity of Rose Bengal encapsulated in zeolitic imidazolate framework-8 (RB@ZIF-8): an innovative approach for the one pot synthesis of highly functionalized tetrahydropyridines and study of their anti-tubercular activity
By exploring the photocatalytic activity of RoseBengal (RB) encapsulated in zeolitic imidazolate framework-8 (ZIF-8) under visible light irradiation, we developed a unique approach for the synthesis of highly functionalized tetrahydropyridines at ambient temperature. This protocol shows generality across various types of benzaldehydes, anilines and alkyl acetoacetates. Feasible operation, availability

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.
