  摘要：

  高烯丙基胺的室温碘环化立体选择性地以高产率递送官能化的2-（碘甲基）氮杂环丁烷衍生物。将反应温度从20°C升高到50°C可以切换反应结果，以实现功能化3-碘吡咯烷衍生物的立体选择性生成。结果表明，这些吡咯烷是通过上述氮杂环丁烷的热异构化反应形成的。伯胺和仲胺可以与碘甲基氮杂环丁烷衍生物反应，以递送稳定的甲基氨基氮杂环丁烷衍生物。随着反应顺序的细微变化，高烯丙基胺可被立体选择性地转化为顺式或反式取代3-氨基吡咯烷衍生物。顺式和反式取代的吡咯烷的立体化学发散性合成支持离子部分，叠氮鎓，异构化途径氮杂环丁烷吡咯烷异构化。在斑马鱼胚胎发育试验中探查了六种氮杂环丁烷衍生物，以通过形态和运动行为表型分析来检测潜在的生物学效应。跨探针分子的作用范围证明了该测定方法适合筛选氮杂环丁烷衍生物。一种被探测的分子外消旋-（（（（顺式）-1-苄基-4-苯基氮杂环丁烷-2-基）甲基）哌啶，在发育测定中表现出特别有趣

  摘要：

  已经开发了一种使用氢化钛和烯丙基锌试剂合成仲胺的一锅直接还原烯丙基化方案。该协议适用于广泛的底物，包括无环酰胺、苯甲酰胺、α,β-不饱和酰胺和内酰胺。从与巴豆基锌试剂反应获得的立体化学结果表明烯丙基化反应通过六元环过渡态进行。(-)-蓖麻胺的全合成是通过遵循此协议来完成的，用于连续立体中心的高度立体选择性构建。

  mild catalytic allylation of carbonyl compounds, applicable to aldehydes, ketones, and imines is developed using allyltrimethoxysilane as the allylating reagent. The reaction proceeds smoothly with 1-10 mol % of CuCl and TBAT in THF at ambient temperature. Mechanism studies indicated that the copper alkoxide, allylfluorodimethoxysilane, and allyltrimethoxysilane are essential to promote the reaction

• Synthesis of Azetidine and Pyrrolidine Derivatives through Selenium-Induced Cyclization of Secondary Homoallylamines − A77Se NMR Study

  Treatment of alpha-alkyl and alpha,alpha-dialkyl homoallylic amines I with PhSeX (X = Cl, Br, 1), in CH3CN containing sodium carbonate produced mixtures of azetidines 2 and pyrrolidines 3. The cyclization also occurred in the absence of Na2CO3, and the corresponding azetidinium and pyrrolidinium salts 2(HX) and 3(HX) were formed in CDCl3 or CH3CN. The crude reaction mixtures were analysed by Se-77 NMR. Each product - 2, 3, 2(HX), and 3(HX) - was characterized by its 77 Se chemical shift, and the product ratios were determined for each reaction. The ratios of azetidine 2 to pyrrolidine 3 increased not only according to the steric hindrance around the alpha-carbon, but also with the nature of the counterion X- (PhSeCl < PhSeBr < PhSeI). Use of PhSeI and amines 1g to 1k (R-1, R-2, not equalH), produced only the azetidinium. salts 2(HI), allowing the isolation of the corresponding azetidines 2, albeit in poor yield. Some reactions were monitored by Se-77 NMR at the beginning of the addition-cyclization process. No intermediates were observed when PhSeI was used, but the thermodynamic addition products 5(Br), 5(HBr), and some dibromose-lenuranes 8 were detected.

• Synthesis of azetidines by electrophilic selenium-induced cyclization of homoallylic benzylamines
  作者：Bénédicte Berthe、Francis Outurquin、Claude Paulmier

  日期：1997.2

  Homoallyl benzylamines, prepared by allylation of the corresponding N-benzylimines, have been subjected to a selenium-induced cyclization under various conditions. At room temperature, the 4-exo and the 5-endo modes are competitive. In acetonitrile, the azetidine has been isolated as the major cyclization product, especially for homoallylamines derived from ketimines. With an excess of selenium reagent, 3-halopyrrolidines have been obtained. (C) 1997 Published by Elsevier Science Ltd.
