    对映体纯的环丙基硼酸酯:辅助对照与底物对照
    摘要:
    稳定的对映体纯的环丙基硼酸酯是由炔烃通过硼氢化-环丙烷化顺序合成的。使用1,3,2-二氧杂硼环烷4进行直接硼氢化反应是最方便的方法,但是,由于侧链功能化,未能提供所需的中间体。使用反应性更高的二环己基硼烷,然后进行氧化和酯交换反应,是一种不错的一锅转化方法。按照Simmons-Smith方案或使用重氮甲烷-钯(II)乙酸酯进行环丙烷化。将对辅助剂1的非对映选择性的影响与侧链中另外的立体异构中心的影响进行比较。

  • Total Synthesis of Oxidized Phospholipids. 3. The (11<i>E</i>)-9-Hydroxy-13-oxotridec-11-enoate Ester of 2-Lysophosphatidylcholine
    作者:Yijun Deng、Robert G. Salomon
    DOI:10.1021/jo000809u
    日期:2000.10.1
    A total synthesis of (11E)-9-hydroxy-13-oxotridec-11-enoate ester of 2-lysophosphatidylcholine (HOT-PC) was devised to facilitate identification of this oxidized phospholipid. A lactone, 8-(3-oxo-1H,6H-2-oxinyl)octanoic acid (1), believed to be generated through an intermediate (11E)-9-hydroxy-13-oxotridec-11-enoic acid (HOT), is produced upon autoxidation of linoleic acid. A synthesis of lactone 1 methyl ester was accomplished from HOT involving a novel trans-cis isomerization that is driven to completion by cyclization to a hemiacetal. An alternative route to this carbon skeleton was also acheived that provides the lactone 1 itself.
  • Synthesis of 1,3-Diynes via Palladium-Catalyzed Reaction of 1,1-Dibromo-1-alkenes
    作者:Wang Shen、Sheela A. Thomas
    DOI:10.1021/ol006282p
    日期:2000.9.1
    Both symmetric and unsymmetric 1,3-diynes were prepared from the palladium-catalyzed reaction of 1,l-dibromo-l-alkenes. The formation of symmetric 1,3-diynes 2 (homocoupling) was catalyzed by a weak ligand, tris(2-furyl)phosphine (TFP), and the addition of catalytic amount of Cul accelerated the reaction. The synthesis of unsymmetric 1,3-diynes 4 (the Sonogashira reaction) required a highly electron rich tris(4-methoxyphenyl)phosphine as the ligand, and Cul promotes the formation of byproduct 1,1-diynyl-1-alkenes 5.
