    Synthesis of Enantioenriched Allenes from 1,1-Cyclopropanediesters
    摘要:
    Highly substituted allenes were obtained by the S(N)2' addition of organocuprate reagents on 2-propargyl-1,1-cyclopropanediesters. This new methodology permits the synthesis of highly enantioenriched allenes as the reaction proceeds with retention of the enantiomeric purity of the starting cyclopropane. The use of higher order cuprates was instrumental in obtaining the reported results.

  • Palladium(0)–Lithium Iodide Cocatalyzed Asymmetric Hydroalkylation of Conjugated Enynes with Pronucleophiles Leading to 1,3-Disubstituted Allenes

    reaction) with pronucleophiles such as dimethyl malonate under the cocatalysis of DTBM-SEGPHOS-ligated palladium and lithium iodide. Although the palladium catalyst ligated with (S)-DTBM-SEGPHOS prefers the formation of (R)-1,3-disubstituted allenes, lithium iodide recovers and increases the intrinsic selectivity producing (S)-allenes by promoting the isomerization of the exo-alkylidene-π-allylpalladium
    在DTBM-SEGPHOS连接的钯和碘化锂的共催化下,将烷基或芳基取代的共轭烯(已通过Sonogashira反应制得)与丙二酸二甲酯等亲核试剂进行加氢烷基化反应,合成了轴向手性的1,3-二取代的烯。尽管与(S)-DTBM-SEGPHOS连接的钯催化剂更倾向于形成(R)-1,3-二取代的烯,碘化锂可以通过促进外-异构体的异构化来回收并增加生成(S)-烯的固有选择性。亚烷基-π-烯丙基钯中间体在亲核取代步骤之前。

    日期:2012.7
    Three′s not a crowd: An intramolecular [2+2+2] cyclization between three different components, allene, alkyne, and alkene, has been realized using a catalytic amount of [Cp*RuCl(cod)] complex (cod=1,5‐cyclooctadiene), and afforded fused‐tricyclic compounds in a highly stereoselective manner.
