  New synthesis of 3-arylpyrrolines

  摘要：

  We present an easy and straightforward synthesis of 3-arylpyrrolines 4a-g by repeated treatment of 4-aryl-1,2,5,6-tetrahydropyridines 2a-g with in-chloroperoxybenzoic acid (MCPBA) and boron trifluoride etherate (BF3-OEt2). The transformation proceeds via epoxidation, ring contraction, Baeyer-Villiger oxidation and elimination reaction and affords 3-arylpyrrolines 4a-g with 61-70% yield. This facile strategy was also used to synthesize racemic baclofen (6). (c) 2005 Elsevier Ltd. All rights reserved.

• A Versatile Route to Unstable Diazo Compounds via Oxadiazolines and their Use in Aryl-Alkyl Cross-Coupling Reactions

  Coupling of readily available boronic acids and diazo compounds has emerged recently as a powerful metal-free carbon-carbon bond forming method. However, the difficulty in forming the unstable diazo compound partner in a mild fashion has hitherto limited their general use and the scope of the transformation. Here, we report the application of oxadiazolines as precursors for the generation of an unstable

  作为一种有效的无金属碳-碳键形成方法，最近出现了易于获得的硼酸和重氮化合物的偶联。然而，迄今为止，以温和的方式形成不稳定的重氮化合物伴侣的困难限制了它们的一般用途和转化范围。在这里，我们报道了恶二唑啉作为前体的应用，它使用流式紫外光解法生成不稳定的重氮化合物家族，并首次用于不同的原去硼和氧化C（sp2）-C（sp3）交叉偶联过程中，具有出色的功能组容忍度。
• Microwave-Assisted Heck Arylations of Non-Activated<i>N</i>-Acyl-3-pyrrolines with Arenediazonium Tetrafluoroborates

  Successful Heck-Matsuda arylations of non-activated olefins applying microwave irradiation as an alternative heating mode are presented. Cleaner reactions were performed with arenediazonium tetrafluoroborates bearing electron-donating and electron-withdrawing groups in good to excellent yields with reaction times reduced from 3.5-18 h to 12-30 min.

  日期：2002.1

  Heck arylation of N-acyl-3-pyrrolines and an N-acyl-tetrahydropyridine with aryldiazonium tetrafluoroborates under phosphine-free conditions proceeded smoothly to give alpha-hydroxycarbamates (hemiaminals) or alpha-alkoxycarbamates which were oxidized to the desired gamma- and delta-lactams. Acidic hydrolysis of the gamma-lactams produced a series of arylated GABA derivatives, including baclofen, a useful therapeutic drug. in only three steps with ail overall yield of 63 76%, Starting from N-acyl-tetrahydropyridine, aryl-delta-lactams and higher homologues of baclofen can be obtained.

  The Cu(OTf)2 catalyzed Ugi-type reactions of N,O-acetals with isocyanides have been described for the synthesis of pyrrolidinyl and piperidinyl 2-carboxamides. 4-Hydroxy-5-substituted-prolinamides can be obtained in high diastereoselectivities (2,4-cis/trans > 19 : 1) and a stereoselective model was proposed for 2,4-cis selectivity. Moreover, 4-F-VH 032, a novel analog of the VHL ligand, was conveniently
