  Brønsted Acid-Promoted Cyclizations of Siloxyalkynes with Arenes and Alkenes

  摘要：

  We have described the first Brønsted acid-mediated cyclizations of siloxyalkynes with simple arenes and alkenes to afford substituted tetralone and cyclohexenone derivatives. The most notable aspect of the carbocyclizations involving siloxyalkynes is the ability to employ a range of substrates that are not restricted to those containing electron-rich arenes and alkenes. The key mechanistic feature of the reaction is the generation of a highly reactive ketenium ion upon protonation of siloxyalkyne. We believe that the low nucleophilicty of the counteranion is crucial for enabling the formation and effective interception of this highly reactive intermediate.

• Aldol Reaction and Robinson-Type Annelation Catalyzed by Lanthanoid Triisopropoxides

  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。
