  通过相转移催化对 2-芳基吲哚进行硝基选择性动态动力学拆分

  摘要：

  本研究提出了由取代的金鸡铵盐作为相转移催化剂催化的 2-芳基吲哚的对转选择性烷基化。在优化的反应条件下，采用多种底物，得到具有高对映选择性的产物。芳环上邻硝基的存在对于高对位选择性至关重要，因为它有利于催化剂和底物之间的良好相互作用。对映选择性的起源揭示了对映体有利的 π-π 相互作用和对不需要的对映体不利的空间张力。

  A method of synthesizing highly optically enriched &agr;-halo-esters comprises reacting acid halides with a cinchona alkaloid catalyst and a base to form intermediate ketenes. The ketenes are reacted with electrophilic halogenating reagents to produce &agr;-halo-esters with high enantiomeric excess. The base can be an inorganic salt. The thus-formed &agr;-halo-esters have utility in synthesizing other optically-pure materials.

  discover biorational natural products-based insecticides, two series (27) of novel 9R/S-acyloxy derivatives of cinchonidine and cinchonine were prepared and assessed for their insecticidal activity against Mythimna separata in vivo by the leaf-dipping method at 1 mg/mL. Among all the compounds, especially derivatives 6l and 6o exhibited the best insecticidal activity with final mortality rates of 75

  摘要 努力发现基于生物理性天然产物的杀虫剂，制备了两类（27）新的辛可尼定和辛可宁的9 R / S-酰氧基衍生物，并通过叶浸法以1 mg的剂量评估了它们对体内Mythimna separata的杀虫活性。/毫升 在所有化合物中，尤其是衍生物6l和6o表现出最好的杀虫活性，最终死亡率分别为75.0％和71.4％。总的来说，游离的9-羟基不是杀虫活性的先决条件，并且C9取代具有良好的耐受性。C8 / 9位的构型对于杀虫活性是重要的，而9 S构型是最佳的。6'-OCH 3 部分不是必需的，也可以将其除去。

  strong nucleophilicity and photochemical activity, can promote the coupling reaction between alcohols and carboxylic acid anhydrides or chlorides to give products under thermal or blue light photochemical conditions. Kinetic studies and density functional theory calculations suggest interesting mechanistic insights for reactions promoted by this acyl-transfer catalytic system.

  酰基转移催化是促进羧酸衍生物形成的常用工具，羧酸衍生物是有机合成中重要的合成前体和目标化合物。但是，已知只有少数结构性基序可以有效催化酰基转移反应。在本文中，我们介绍了基于托酚酮骨架的不同的酰基转移催化范式。我们显示，对羟基苯甲酸酯盐由于其强大的亲核性和光化学活性，可以促进醇与羧酸酐或氯化物之间的偶联反应，从而在热或蓝光光化学条件下产生产物。动力学研究和密度泛函理论计算表明，该酰基转移催化体系促进了反应的有趣机理。

  Stereochemistry, products, and driving forces of the “first and second Cinchona rearrangement” have been investigated and a unified theory is presented. The first cage expansion affords [3.2.2]azabicyclic α-amino ether and is formulated via a configurationally stable bridgehead iminium ion and quasiequatorial nucleophilic attack. The second cage expansion affords β-functionalized [3.2.2]azabicycles

  研究了“第一和第二次金鸡纳重排”的立体化学，产物和驱动力，并提出了统一的理论。第一次笼扩展提供了[3.2.2]氮杂双环α-氨基醚，并通过构型稳定的桥头亚胺离子和准四亲核攻击进行配制。第二个笼扩展提供了β-官能化的[3.2.2]氮杂双环。在这种情况下，假定存在非经典的氮桥阳离子，以说明保持构型和保持架扩展的潜在可逆性。第二种重新排列因所谓的肚带而受到青睐在三氟乙醇中的碱（6'-R = H）。在所有情况下，立体电子因素，C9处的电子需求，基态构型和溶剂类型都是至关重要的。描述了从9- nat前体制备9-表位构型的金鸡纳生物碱的两步方案。
• Inversion of enantioselectivity for the hydrogenation of ethyl pyruvate in the gas-phase over Pt/SiO2 modified with derivatives of hydroquinidine
  作者：N DUMMER、R JENKINS、X LI、S BAWAKED、P MCMORN、A BURROWS、C KIELY、R WELLS、D WILLOCK、G HUTCHINGS

  Ethyl pyruvate was hydrogenated as a gas-phase reactant over 2.5% Pt/SiO2 premodified with hydroquinidine 4-chlorobenzoate at two concentrations (0.85 and 8.5 mM g(cat)(-1)). The sense of enantioselectivity changed as a function of the modifier concentration. At low modifier concentrations, the (S)-lactate is the preferred product, and at higher concentrations, (R)-lactate is favoured. The lower concentration yielded an enantiomeric excess (ee) of 15% (S)-ethyl lactate in contrast to 17% (R)-lactate for the higher concentration. A range of hydroquinidine and hydroquinine derivatives were evaluated at these concentrations; the results suggest that the carbonyl group of the ester linkage at the C(9) position was required to promote the observed inversion of enantioselectivity. In a subsequent set of experiments, Bi3+ was adsorbed onto the Pt/SiO2 catalyst before the premodification step; these ions are considered to adsorb preferentially on high-energy surface sites (e.g., corner sites or step edges). Increasing Bi3+ concentration decreased the degree of inversion until the effect was lost. On the basis of high-resolution electron microscopy (HREM) comparisons of these Pt/SiO2 and Bi-PtlSiO(2) catalysts, the inversion effect is discussed in terms of the interaction of the substrate and modifier with the catalyst surface.
