  • Organocatalytic Enantioselective Selenosulfonylation of a C–C Double Bond To Form Two Stereogenic Centers in an Aqueous Medium
    作者:Zhili Chen、Fangli Hu、Shengli Huang、Zhengxing Zhao、Hui Mao、Wenling Qin
    DOI:10.1021/acs.joc.9b00973
    日期:2019.6.21
    Organocatalytic selenosulfonylation of the C–C double bond of α,β-unsaturated ketones to construct two contiguous stereogenic centers in an aqueous medium was described. A series of α-selenyl and β-sulfonyl ketones with various functional groups were synthesized in good yields and enantioselectivities with saturated NaCl solution as the solvent. In addition, this protocol had been successfully scaled
    描述了α,β-不饱和酮的CC双键的有机催化硒代磺酰化反应,可在水性介质中构建两个连续的立体异构中心。以饱和NaCl溶液为溶剂,以良好的收率和对映选择性合成了一系列具有各种官能团的α-硒烯基和β-磺酰基酮。此外,该协议已通过简单的后处理程序成功扩展到十进制规模。

    ring was essential to control the stereoselectivity of the reaction. Michael adducts were obtained in high yields and moderate enantioselectivities in the reaction between 4-nitroindole and various Michael acceptors in the presence of cinchona alkaloid based phase-transfer catalysts. In addition to outlining the scope and limitations of the method, the geometries of the transition states of the reaction
    研究了具有各种迈克尔受体的取代吲哚的不对称相转移催化的N-烷基化。通过UV-Vis分光光度滴定法测定乙腈中硝基吲哚的酸度。在氮杂-迈克尔反应中,酸度和反应性之间基本上没有相关性。吲哚环上硝基的位置对于控制反应的立体选择性至关重要。在基于金鸡纳生物碱的相转移催化剂存在下,4-硝基吲哚与各种迈克尔受体之间的反应以高收率和中等对映选择性获得迈克尔加合物。除了概述该方法的范围和局限性之外,还计算了反应过渡态的几何形状。
  • Decarboxylative Allylation of Glyoxylic Acids with Diallyl Carbonate
    作者:Filipe Manjolinho、Matthias F. Grünberg、Nuria Rodríguez、Lukas J. Gooßen

    ketones. The key advantage of the new reaction protocol is that preformation of the allyl esters is not required. The reaction is believed to proceed via phosphane-mediated decarboxylation of the α-oxocarboxylates, leading to acyl anion equivalents that are allylated within the coordination sphere of the palladium catalyst. Under the reaction conditions, the double bond then migrates into conjugation
    发现由 Pd(PPh3)4 和 P(pTol)3 组成的催化剂体系可有效促进 α-氧代羧酸与碳酸二烯丙酯的分子间脱羧偶联,得到 α,β-不饱和酮。新反应方案的主要优点是不需要预先形成烯丙酯。据信,该反应通过磷烷介导的 α-氧代羧酸酯脱羧进行,导致在钯催化剂的配位范围内烯丙基化的酰基阴离子等价物。在反应条件下,双键然后迁移到与羰基共轭。

    日期:2007.12.1
    Thiol esters and boronic acids react to produce ketones under aerobic conditions in the presence of catalytic quantities of a CuI or CuII salt. The reaction occurs at reasonable rates between room temperature and 50 degrees C at neutral pH using thiol esters derived from bulky 2 degrees amides of thiosalicylamides such as those based on N-tert-butyl-2-mercaptobenzamide. In this mechanistically unprecedented
    在催化量的 CuI 或 CuII 盐存在下,硫醇酯和硼酸在有氧条件下反应生成酮。使用衍生自庞大的 2 度硫代水杨酰胺(如基于 N-叔丁基-2-巯基苯甲酰胺的那些)的硫羟酸酯,反应在室温和 50 摄氏度之间以合理的速率在中性 pH 下发生。在这个机制上前所未有的反应体系中,碳-碳键的形成是通过硫羟酸酯和硼酸在铜上的模板化而发生的;该系统在有氧条件下在铜中具有催化作用。
  • Steric Tuning of Silylacetylenes and Chiral Phosphine Ligands for Rhodium-Catalyzed Asymmetric Conjugate Alkynylation of Enones

    日期:2008.2.6
    Rhodium-catalyzed asymmetric conjugate alkynylation of α,β-unsaturated ketones giving β-alkynylketones took place in high yields with high enantioselectivity. The reaction was realized by use of (triisopropylsilyl)acetylene combined with (R)-DTBM-segphos as a chiral phosphine ligand, where the sterically bulky substituents on the silicon and phosphorus atoms suppress the alkyne dimerization.
    铑催化的 α,β-不饱和酮的不对称共轭炔基化以高产率和高对映选择性发生 β-炔基酮。该反应是通过使用(三异丙基甲硅烷基)乙炔与(R)-DTBM-segphos 结合作为手性膦配体来实现的,其中硅和磷原子上的空间庞大的取代基抑制炔二聚化。
