  同手性锂酰胺用于不对称合成β-氨基酸

  摘要：

  衍生自α-甲基苄胺的仲手性锂酰胺会经历高度非对映选择性的共轭加成反应，形成一系列α，β-不饱和酯。通过连续的N-去苄基化和酯水解，可以轻松释放相应的β-氨基酸，从而提供（R）-β-氨基丁酸，（R）-β-氨基戊酸，（S）-β-亮氨酸，（R） -β-氨基辛酸，（S）-β-苯丙氨酸，（S）-β-酪氨酸甲基醚，（S）-β-酪氨酸盐酸盐和（S）-β-（2-甲氧基苯基）-β-氨基丙酸高产和高ee的酸。该程序在天然产物合成中的应用（R证明了）-β-DOPA和（R）-β-赖氨酸。还描述了简化的一锅反应规程的开发，该规程适用于同级手性β-氨基酯的多克规模合成。

  通过铜催化的烯基硼酸与磷叶立德偶联反应制备α，β-不饱和酯和α，β-不饱和γ-酮酯的可调谐路线

  摘要：

  通过在温和的条件下通过铜催化的磷化磷与烯基硼酸的氧化偶联反应，开发了一种可调谐策略，以高至极好的收率制备α，β-不饱和酯和α，β-不饱和γ-酮酯。不加水的反应得到α，β-不饱和酯，酮和酰胺，而α，β-不饱和γ-酮酯，1,4-α，β-不饱和二酮和α，β-不饱和γ-酮酰胺是使用5.0当量时获得。水。高2 O 18标记实验表明，水在α，β-不饱和γ-酮酸酯的形成中起着重要作用。在机理研究的基础上，提出了α，β-不饱和酯和α，β-不饱和γ-酮酯的合理形成机理。salts盐也可以代替磷化磷化物直接用作偶联伴侣。该反应表现出广泛的底物范围，良好的官能团耐受性，良好的区域选择性和多种偶联产物。

• A Convenient Method for Olefination of <i>vic</i>-Diols by Lithium Iodide <i>via</i> Cyclic Sulfates
  作者：Doo Jang、Yung Joo

  DOI：10.1055/s-1997-782

  日期：1997.3

  Reaction of cyclic sulfates of vic-diols with lithium iodide in acetone produced the corresponding olefins in excellent isolated yields at low temperature. Cyclic sulfates of trans-diols gave trans-alkenes exclusively. Cyclic sulfates of cis-diols gave a mixture of cis- and trans-alkenes. The reaction offers mild conditions and easy work-up procedures.

• A Stoichiometric Haloform Coupling for Ester Synthesis with Secondary Alcohols

  A general haloform coupling reaction for the synthesis of esters from methyl ketones is reported using one equivalent of alcohol. Detailed kinetic modelling studies demonstrate that the key intermediates are formed under equilibrium, which led to the development of conditions that are amenable to secondary alcohols.

• Polyhydroxyalkanoate-based 3-hydroxyoctanoic acid and its derivatives as a platform of bioactive compounds

  A library of 18 different compounds was synthesized starting from (R)-3-hydroxyoctanoic acid which is derived from the bacterial polymer polyhydroxyalkanoate (PHA). Ten derivatives, including halo and unsaturated methyl and benzyl esters, were synthesized and characterized for the first time. Given that (R)-3-hydroxyalkanoic acids are known to have biological activity, the new compounds were evaluated for antimicrobial activity and in vitro antiproliferative effect with mammalian cell lines. The presence of the carboxylic group was essential for the antimicrobial activity, with minimal inhibitory concentrations against a panel of bacteria (Gram-positive and Gram-negative) and fungi (Candida albicans and Microsporum gypseum) in the range 2.8-7.0 mM and 0.1-6.3 mM, respectively. 3-Halogenated octanoic acids exhibited the ability to inhibit C. albicans hyphae formation. In addition, (R)-3-hydroxyoctanoic and (E)-oct-2-enoic acids inhibited quorum sensing-regulated pyocyanin production in the opportunistic pathogen Pseudomonas aeruginosa PAO1. Generally, derivatives did not inhibit mammalian cell proliferation even at 3-mM concentrations, while only (E)-oct-2-enoic and 3-oxooctanoic acid had IC50 values of 1.7 and 1.6 mM with the human lung fibroblast cell line.
• A Convenient Method for the Synthesis of Alkenes from <i>Vic</i>-diols <i>via</i> Cyclic Sulfates with Magnesium Iodide
  作者：Doo Ok Jang、Yung Hyup Joo

  DOI：10.1080/00032719808006486

  日期：1998.3.1

  Reaction of cyclic sulfates of vic-diols with magnesium iodide in acetonitrile produced the corresponding olefins in excellent isolated yields at room temperature. Cyclic sulfates of trans-diols gave trans-alkenes exclusively. Cyclic sulfates of cis-diols gave a mixture of cis- and trans-alkenes. However, the cyclic sulfate of cyclic cis-diol afforded the corresponding cis-alkene only.
• A Facile Route to Olefins from<i>Vic</i>-Diols<i>Via</i>Cyclic Sulfates with Triphenylphosphine and Iodine

  日期：1997.7

  Treatment of cyclic sulfates of vic-diols with triphenylphosphine and iodine offers the corresponding olefins in high yields at room temperature. Both cyclic sulfates of d,l-hydrobenzoin and meso-hydrobenzoin give trans-stilbene.
