  摘要：

  [反应：请参阅文本] 1-芳基-4-苯基-1-氮杂二烯在回流的苯中的烯丙酯的C2，C3π键上进行容易的区域选择性[4 + 2]环加成，生成的加合物经历1， 3-H转变得到新颖的2-烷基-1-芳基-3-乙氧基羰基-4-苯基-1,4-二氢吡啶（78-97％）。然而，当反应在室温下进行时，除了[4 + 2]加成以外，还涉及[2 + 2]的加成方式，涉及氮杂二烯的C ＝ N和烯丙酸酯的C 3，C 4π键。所得的N-芳基-2-乙氧基-羰基-亚甲基-4-苯乙烯基氮杂环丁烷（17-28％）在硅胶上进行重组，得到2-环己烯-1-酮。

  An efficient approach for one‐pot three‐component reaction of aromatic amines, α,β‐unsaturated aldehydes and β‐keto esters using magnetic nanocrystalline Fe3O4 as a catalyst has been described. The corresponding 1,4‐dihydropyridines are obtained in good yields under mild conditions. In addition, the catalyst can be recovered with a magnet and reused at least five consecutive cycles without appreciable

  three-component domino reaction between aromatic amines, α,β-unsaturated aldehydes, and ethyl acetoacetate, providing an efficient new entry into 1,4-dihydropyridines. This new reaction requires very mild reaction conditions, has water as the only side product and is complementary to the classical Hantzsch synthesis in that it is well suited to the preparation of N-aryl-5,6-unsubstituted dihydropyridines.

  日期：2008.4

  An organocatalysed protocol for one-pot synthesis of 1,4-dihydropyridines via three-component coupling of cinnamaldehyde, aniline and beta-keto esters under solvent free conditions at ambient temperature is reported. The reaction is generally very fast and the products are obtained in high yield. The catalytic activity of small organic molecules like amino acids (acidic, basic and neutral), ephedrine and cinchona alkaloids was studied. (c) 2008 Elsevier Ltd. All rights reserved.
