    摘要:
    丙二烯是一类非常重要的化合物,对丙二烯的简单,有效和高度对映选择性的合成策略的发展引起了广泛的兴趣。沿着这条线,众所周知,芳基取代的烯可以很容易地消旋,因此很难在高ee值下制备。在此,开发了一种高效的钯催化丙二酸酯与外消旋的4-芳基-2,3-丁二烯基碳酸酯的亲核烯丙基化反应。mono vs的选择性问题。已经解决了2非取代丙二酸酯的双烯丙基化作用。通过利用([R )- ( - ) - DTBM-SEGPHOS(5,5'-双[二(3,5-二-吨[-丁基-4-甲氧基苯基)膦] -4,4'-bi-1,3-苯并二恶唑)作为手性配体,已制备了各种芳基取代的烯和双烯烯,收率良好至优异,在温和的条件下具有高化学选择性和对映选择性反应条件。已经证明了Au催化的环异构化和APK(烯丙基Pauson–Khand)反应可提供光学活性的单环和双环产物。

  • 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

  • Synthesis of Enantioenriched Allenes from 1,1-Cyclopropanediesters
    作者:Pascal Cérat、Philipp J. Gritsch、Sébastien R. Goudreau、André B. Charette
    DOI:10.1021/ol902766f
    日期:2010.2.5
    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.
  • Pd-Catalyzed Cascade Cyclization by Intramolecular Heck Insertion of an Allene–Allylic Amination Sequence: Application to the Synthesis of 3,4-Fused Tricyclic Indoles
    作者:Shun-ichi Nakano、Naoya Inoue、Yasumasa Hamada、Tetsuhiro Nemoto
    DOI:10.1021/acs.orglett.5b00973
    日期:2015.6.5
    A novel Pd-catalyzed cascade cyclization by intramolecular Heck insertion of an alleneallylic amination sequence was developed. Allenes tethered to ortho-iodoaniline derivatives at the meta-position were reacted with 5-10 mol % of Pd catalyst and 4 equiv of K2CO3 in DMSO at 90 degrees C, producing 3,4-fused tricyclic 3-alkylidene indoline derivatives in moderate to excellent yield. The reaction products were divergently transformed into three types of 3,4-fused tricyclic indole derivatives, successfully demonstrating the versatile properties of the reaction products.

    that aryl‐substituted allenes may be readily racemized, thus, difficult to prepare in high ee. Herein, an efficient palladium‐catalyzed nucleophilic allenylation of malonates with racemic 4‐aryl‐2,3‐butadienyl carbonates has been developed. The selectivity issue of mono‐ vs. bis‐allenylation with 2‐non‐substituted malonates has been addressed. By utilizing (R)‐(–)‐DTBM‐SEGPHOS (5,5'‐bis[di(3,5‐di‐
