    苄胺作为氢转移剂:通过1,5-氢转移,钴催化的化学选择性C = C键还原β-三氟甲基化的α,β-不饱和酮。
    摘要:
    报道了使用苄胺作为涉及分子内1,5-氢转移的氢转移剂,有效地钴催化的β-CF3-α,β-不饱和酮的化学选择性还原。反应可在相对较宽的底物范围内顺利进行,包括带有芳香杂环的底物,例如呋喃环系统,产率高(74-92%)。这为一锅法合成β-CF3饱和酮提供了一种有效的方法。该方法还适用于选择性C = C还原不含β-CF3-取代基的其他烯酮底物,其中β-取代或β,β-二取代的烯酮是可以耐受的,从而以高收率获得了所需的产物(72-75 %)。机理研究表明该反应涉及1,5-氢转移。

  • Regioselective 1,4-trifluoromethylation of α,β-unsaturated ketones via a <i>S</i>-(trifluoromethyl)diphenylsulfonium salts/copper system

    Regioselective conjugate 1,4-trifluoromethylation of alpha,beta-unsaturated ketones by the use of shelf-stable electrophilic trifluoromethylating reagents, S-(trifluoromethyl)diphenylsulfonium salts and copper under mild conditions is described. A wide range of acyclic aryl-aryl-enones and aryl-alkyl-enones were converted into beta-trifluoromethylated ketones in low to moderate yields.

    between an allylic anion and the conjugate acid of the base results in efficient transfer of chirality. Through this mechanism, stereochemical information contained in the allylic alcohols is transferred to the ketone products. The stereospecific isomerization is also applicable for the first time to allylic ethers, yielding synthetically valuable enantioenriched (up to 97% ee) enol ethers.
    已开发出一种用于烯丙醇和烯丙醚异构化的温和碱催化策略。实验和计算研究表明,当存在碱性添加剂时,不需要过渡金属催化剂。与在碱性条件下使用过渡金属的情况一样,仅由碱催化的异构化也遵循立体定向途径。该反应由限速去质子化引发。在烯丙基阴离子和碱的共轭酸之间形成紧密离子对导致手性的有效转移。通过这种机制,烯丙醇中包含的立体化学信息被转移到酮产品中。立体有择异构化也首次适用于烯丙基醚,

  • Rhodium(<scp>i</scp>)-catalyzed 1,4-conjugate arylation toward β-fluoroalkylated electron-deficient alkenes: a new entry to a construction of a tertiary carbon center possessing a fluoroalkyl group

    Treatment of β-fluoroalkylated-α,β-unsaturated ketones with 1.2 equiv. of various arylboronic acids in the presence of 5 mol% of [Rh(COD)2]BF4 and 6 mol% of (S)-BINAP in toluene/H2O (v/v = 4/1) at the reflux temperature for 3 h gave the corresponding Michael adducts in high yields with over 90% enantioselectivity. Though other electron-deficient alkenes, such as vinylsulfone and vinylphosphonate, were found to be much less reactive in the rhodium-catalyzed conjugate addition with arylboronic acids, the reaction of various arylstannanes toward such electron-deficient alkenes took place very smoothly to afford the corresponding adducts in high yields.
    在甲苯/H2O(v/v = 4/1)溶液中,加入 5 摩尔的[Rh(COD)2]BF4 和 6 摩尔的(S)-BINAP,在回流温度下,用 1.2 等份的各种芳基硼酸处理δ-氟烷基化-δ,δ-不饱和酮 3 小时,可得到相应的迈克尔加合物,产率高,对映选择性超过 90%。虽然其他缺电子烯类,如乙烯基砜和乙烯基膦酸,在铑催化的芳基硼酸共轭加成反应中反应性要差得多,但各种芳基锡烷与这些缺电子烯类的反应非常顺利,能以高产率得到相应的加合物。
