  • Aldol Reaction and Robinson-Type Annelation Catalyzed by Lanthanoid Triisopropoxides
    作者:Tamon Okano、Yoshikazu Satou、Motoshi Tamura、Jitsuo Kiji
    DOI:10.1246/bcsj.70.1879
    日期:1997.8
    Lanthanoid triisopropoxides are active catalysts for aldol reactions. Aldehydes give the corresponding β-hydroxyaldehydes at low temperatures in good yields, whereas ketones are less reactive, but form condensation products at high temperatures. Exceptionally, γ- or δ-diketones easily undergo condensation to give five- and six-membered unsaturated ketones in high yields. The lanthanoid propoxides, catalyzing the Michael addition of ketones to α,β-unsaturated ketones, which give δ-diketones, are also good catalysts for the Robinson-type annelation. In these reactions, the catalytic activity of the lanthanum propoxide is higher than those of the heavy lanthanoid propoxides, and is almost comparable to that of sodium isopropoxide. Since aluminum triisopropoxide shows poor activity, the lanthanoid propoxides are considerably basic for trivalent metal alkoxides.
    镧系三异丙醇盐是醛醇反应的活性催化剂。在低温下,醛能够高效地生成相应的β-羟基醛,而酮的反应活性较低,但在高温下会形成缩合产物。特别地,γ-或δ-二酮很容易发生缩合反应,以高产率生成五元和六元的非饱和酮。镧系异丙醇盐还具有催化酮对α,β-非饱和酮的迈克尔加成反应,这种反应会生成δ-二酮,同时也是罗宾逊型环加成反应的良好催化剂。在这些反应中,镧异丙醇盐的催化活性高于重镧系异丙醇盐,几乎可与钠异丙醇盐相媲美。由于铝三异丙醇盐的活性较差,镧系异丙醇盐相对于三价金属醇盐具有相当强的碱性。
  • 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。

    improvement in the methods for addition-elimination reactions via activation of carbonyl functionality. In this paper, an advanced methodology for the direct esterification of carboxylic acids and alcohols, and for aldol condensation of aldehydes using widely available, inexpensive, and metal-free 1,3-dibromo-5,5-dimethylhydantoin under neat reaction conditions is reported. The method is air- and moisture-tolerant
