  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.

  Compared with the ripeness of olefin metathesis, exploration of the construction of carbon-carbon double bonds through the catalytic carbonyl-olefin metathesis reaction remains stagnant and has received scant attention. Herein, a highly efficient AuCl3 -catalyzed intramolecular ring-closing carbonyl-olefin metathesis reaction is described. This method features easily accessible starting materials,

  与烯烃复分解的成熟相比，通过催化羰基-烯烃复分解反应构建碳-碳双键的研究仍然停滞不前，受到关注的很少。在此，描述了高效的AuCl 3催化的分子内闭环羰基-烯烃复分解反应。该方法具有易于获得的原料，操作简单，对官能团的耐受性强和反应时间短的特点，并以优异的产率提供了目标环戊烯，多环化合物，苯并碳环化合物和N-杂环衍生物。

  carbonyl–olefin metathesis is an ongoing challenge in organic synthesis. Reported herein is an FeCl3‐catalyzed ring‐closing carbonyl–olefin metathesis. The protocol allows access to a range of carbo‐/heterocyclic alkenes with good efficiency and excellent trans diastereoselectivity. The methodology presents one of the rare examples of catalytic ring‐closing carbonyl–olefin metathesis. This process is

  利用催化羰基-烯烃复分解反应是有机合成中的一项持续挑战。本文报道的是FeCl 3催化的闭环羰基烯烃复分解反应。该协议允许以良好的效率和出色的反非对映异构选择性访问各种碳/杂环烯烃。该方法学是催化闭环羰基烯烃复分解的罕见例子之一。提议通过FeCl 3催化的氧杂环丁烷的形成，然后进行逆向开环以提供易位产物来进行此过程。

  The carbonyl–olefin metathesis (COM) reaction is an attractive approach for the formation of a new carbon–carbon double bond from a carbonyl precursor. In principle, this reaction can be promoted by the activation of the carbonyl group with a Brønsted acid catalyst; however, it is often complicated as a result of unwanted side reactions under acidic conditions. Thus, there have been only a very few

  羰基-烯烃复分解 (COM) 反应是从羰基前体形成新的碳-碳双键的一种有吸引力的方法。原则上，该反应可以通过用布朗斯台德酸催化剂活化羰基来促进；然而，由于在酸性条件下发生不希望的副反应，它通常很复杂。因此，只有极少数的布朗斯台德酸催化 COM 反应的例子，所有这些都需要专门设计的装置。在此，我们报告了一种新的实用均相布朗斯台德酸催化方案，该方案使用硝基甲烷（一种容易获得的溶剂）来促进分子内闭环 COM 反应。
