  • Synthesis of α,β-Unsaturated Carbonyl Compounds by Titanium Tetraalkoxide-Induced Aldol Condensation under Neutral Conditions
    作者:Rainer Mahrwald、Hans Schick
    DOI:10.1055/s-1990-26952
    日期:——
    Aldehydes and ketones, when treated with titanium tetraalkoxides in a hydrocarbon solvent at 20-140°C, undergo aldol condensation to give a, α,β-unsaturated carbonyl compounds. To avoid Meerwein-Ponndorf-Verley type reduction of the carbonyl compounds, titantium tetra-tert-butoxide is used, if the reaction is carried out at higher temperatures. In all other cases titanium tetraisopropoxide can be successfully employed. The outlined procedure offers the possibility of performing aldol condensations under neutral conditions.
    醛和酮在20-140°C的烃溶剂中与四烷氧基钛处理时,会发生醇缩反应,生成α,β-不饱和羰基化合物。为了避免羰基化合物的Meerwein-Ponndorf-Verley型还原,如果反应在较高温度下进行,则使用四-tert-丁氧钛。在所有其他情况下,四异丙氧钛可以成功使用。该方法提供了在中性条件下进行醇缩反应的可能性。

  • RuPHOX-Ru-Catalyzed Selective Asymmetric Hydrogenation of Exocyclic α,β-Unsaturated Pentanones
    作者:Jing Li、Yue Zhu、Yufei Lu、Yanzhao Wang、Yangang Liu、Delong Liu、Wanbin Zhang
    DOI:10.1021/acs.organomet.9b00366
    日期:2019.10.28
    A RuPHOX-Ru catalyzed selective asymmetric hydrogenation of exocyclic α,β-unsaturated ketones has been developed, furnishing the corresponding chiral exocyclic allylic alcohols in high yields and with up to >99.5% ee. The reaction could be performed on a gram scale with a relatively low catalyst loading (up to 10000 S/C) without any loss in reaction activity and enantioselectivity. The resulting hydrogenated
    已开发出RuPHOX-Ru催化的环外α,β-不饱和酮的选择性不对称氢化,可提供高收率和最高> 99.5%ee的相应手性环外烯丙基醇。该反应可以以克级进行,具有相对较低的催化剂负载量(最高10000 S / C),而没有任何反应活性和对映选择性的损失。所得的氢化产物可以容易地转化为具有高不对称性能的几种生物活性化合物。不对称方案为合成手性环外烯丙基醇提供了一种有效的方法。

  • Asymmetric hydrogenation of unsaturated carbonyl compounds catalyzed by BINAP-Ru(II) complexes. Enantioselective synthesis of γ-butyrolactones and cyclopentanones
    作者:Tetsuo Ohta、Tsutomu Miyake、Nobuo Seido、Hidenori Kumobayashi、Susumu Akutagawa、Hidemasa Takaya
    DOI:10.1016/s0040-4039(00)92330-x
    日期:1992.1
    Asymmetric hydrogenation of 2- and 4-alkylidene-γ-butyrolactones and 2-alkylidenecyclopentanones catalyzed by BINAPRu(II) complexes affords the corresponding γ-butyrolactones and cyclopentanones in 94–98% ee. Hydrogenation of (E)- and (Z)-2-propylidene-γ-butyrolactone catalyzed by the same catalyst gave the products with the same absolute configuration and in almost equal enantioselectivities, which
    BINAP-Ru(II)配合物催化2-和4-亚烷基-γ-丁内酯和2-亚烷基环戊酮的不对称加氢,可得到94-98%ee的相应γ-丁内酯和环戊酮。在同一催化剂下催化的(E)-和(Z)-2-亚丙基-γ-丁内酯的加氢反应得到的产物具有相同的绝对构型和几乎相等的对映选择性,这表明烯烃的几何形状不会影响立体化学和对映选择性。
