    摘要:
    染成二烯:通过标题反应合成了1,3-二烯(参见方案; Tf =三氟甲磺酰基)。初步研究支持了一种机理上截然不同的途径,该途径涉及从阳离子乙烯基钯(II)中间体中初步消除β-氢化物,随后对相应的异戊烯中间体进行区域特异性加氢钯化以及最终消除β-氢化物。

  • Stereocontrolled Synthesis of 13-Substituted Retinoic Acids by Palladium-Catalyzed Coupling Reaction of Alkenyl Stannane with Vinyl Triflate
    作者:Akimori Wada、Kouki Fukunaga、Masayoshi Ito
    DOI:10.1055/s-2001-14908
    日期:——
    A novel method for the stereoselective synthesis of all-E-, 13Z- and 9Z-retionic acid esters was developed by palladium-catalyzed cross coupling reactions of tetraenyl stannanes with E- or Z-vinyl triflates in good yields. Applying this methodology, 13-substituted all-E- and 9Z-retionic acids were prepared in satisfactory yields.
    一种新的立体选择性合成全E-、13Z-和9Z-维甲酸酯的方法,通过钯催化的四烯基锡与E型或Z型乙烯基三氟甲磺酸酯的交叉耦合反应,产率良好。应用此方法,成功以满意的产率制备了13-取代的全E-和9Z-维甲酸。
  • Stereoselective Synthesis of Acetoacetate-Derived Enol Triflates
    作者:David Babinski、Omid Soltani、Doug E. Frantz
    DOI:10.1021/ol8010002
    日期:2008.7.3
    A highly stereoselective method for preparing ( Z)- and ( E)-enol triflates derived from substituted acetoacetate derivatives is described. The salient feature of this methodology is the use of Schotten-Baumann-type conditions to control enolate geometry using either aqueous LiOH ( Z-selective) or aqueous (Me)(4)NOH ( E-selective) in combination with triflic anhydride to provide a practical and predictable
    描述了用于制备衍生自取代的乙酰乙酸酯衍生物的(Z)-和(E)-烯醇三氟甲磺酸酯的高度立体选择性的方法。该方法的显着特征是使用Schotten-Baumann型条件通过使用LiOH水溶液(Z选择性)或(Me)(4)NOH水溶液(E选择性)与三氟甲磺酸酐组合来控制烯醇几何形状,以提供这些有价值的基材的实用且可预测的方法。
  • Unified Approach to Substituted Allenoates via Pd-Catalyzed β-Hydride Elimination of (<i>E</i>)-Enol Triflates
    作者:Marie El Arba、Sara E. Dibrell、Ian T. Crouch、Doug E. Frantz
    DOI:10.1021/acs.orglett.7b02736
    日期:2017.10.6
    A robust synthesis of allenoates via a Pd-catalyzed beta-hydride elimination of (E)-enol triflates is presented. Salient features of this method include low catalyst loadings, mild reaction conditions, and the ability to access all four patterns of substituted allenoates from a single substrate class.
  • Preparation and biological activity of 13-substituted retinoic acids
    作者:Akimori Wada、Kouki Fukunaga、Masayoshi Ito、Yukari Mizuguchi、Kimie Nakagawa、Toshio Okano
    DOI:10.1016/j.bmc.2004.04.047
    日期:2004.7
    13-Demethyl or 13-substituted all-E- and 9Z-retinoic acids were synthesized using a palladium-catalyzed coupling reaction of enol triflates and tributylstannylolefins. Their biological activities were then measured. The 13-ethyl analogs exhibited approximately one-half of the antiproliferative and differentiation-inducing activity of ATRA in HL-60 cells. In contrast, in the 9Z-derivatives, all analogs, except for the 13-butyl derivatives, showed apoptosis-inducing activity. (C) 2004 Elsevier Ltd. All rights reserved.
