  • An Efficient and Extremely Mild Catalyst System, Combined Use of Trityl Chloride and Tin(II) Chloride, in the Aldol and Michael Reactions
    作者:Teruaki Mukaiyama、Shu Kobayashi、Masanori Tamura、Yukihiro Sagawa
    DOI:10.1246/cl.1987.491
    日期:1987.3.5
    The aldol reaction of silyl enol ethers with acetals or aldehydes, and the Michael reaction of silyl enol ethers with α,β-unsaturated ketones are efficiently catalyzed by the combined use of trityl chloride and tin(II) chloride under extremely mild conditions.
    硅烷基烯醇醚与缩醛或醛的羟醛反应,以及甲硅烷基烯醇醚与 α,β-不饱和酮的迈克尔反应通过三苯甲基氯氯化锡 (II) 的联合使用在极其温和的条件下有效催化。
  • Lithium Alkoxide-promoted Michael Reaction between Silyl Enolates and α,β-Unsaturated Carbonyl Compounds
    作者:Teruaki Mukaiyama、Takashi Tozawa、Hidehiko Fujisawa
    DOI:10.1246/cl.2004.1410
    日期:2004.11
    Michael reaction between silyl enolates and 0',/3-unsaturated carbonyl compounds by using a catalytic amount of Lewis base such as lithium alkoxide in DMF proceeds smoothly to afford the corresponding Michael-adducts in good yields with moderate to high diastereoselectivities. This reaction can be reasonably explained by considering an alkoxide anion-initiated autocatalytic process.
    通过使用催化量的路易斯碱(如 DMF 中的醇),甲硅烷基烯醇化物和 0',/3-不饱和羰基化合物之间的迈克尔反应顺利进行,以良好的收率提供相应的迈克尔加合物,并具有中等至高的非对映选择性。通过考虑醇盐阴离子引发的自催化过程,可以合理地解释该反应。
  • Novel reactive silyl enolates. Highly stereoselective aldol and Michael reactions without catalysts
    作者:Shu Kobayashi、Koichi Nishio
    DOI:10.1021/jo00062a002
    日期:1993.5
    Novel silyl enolates, prepared in situ from ketones and dimethylsilyl ditriflate (Me2Si(OTf)2) in the presence of a tertiary amine, reacted smoothly with electrophiles such as aldehydes, acetals, or alpha,beta-unsaturated ketones without catalyst at -78-degrees-C to afford the corresponding adducts in high yields and with high selectivities.
