    名称:
    Asymmetric formation of CN bonds in chiral enol ethers
    摘要:
    Attack of EtO2CN on an enol ether carrying (S,S)-hydrobenzoin as chiral auxiliary gives diastereoselective aziridination with diastereomeric excess > 95%. Easy subsequent hydrolysis gives partially racemised alpha-amino ketone 4. Other chiral auxiliaries does not allow isolation of intermediate aziridines and the alpha-amino ketone is isolated with a 75:25 enantiomeric ratio. The thermolysis of EtO2CN3 in most of the same enol ethers gives the acetals of the alpha-amino ketone with prevailing opposite configuration at the new formed chiral centre.

    摘要:
    通过使用二醇,烷氧基硅烷和催化量的三甲基甲硅烷基三氟甲磺酸盐(TMSOTf),羰基化合物可以在温和的条件下以高收率转化为乙缩醛。在不合成甲硅烷基化二醇的情况下进行的该方法是Noyori方法的更方便的改编。该缩醛化不仅适用于简单的羰基化合物,而且适用于共轭的羰基化合物。而且,包括固相负载的化合物在内的各种TMS化合物代替烷氧基硅烷对于该方法都是有效的。

  • Oxidation of homochiral ketals by rhenium(VII) oxide. V
    作者:Suhan Tang、Robert M. Kennedy
    DOI:10.1016/s0040-4039(00)74753-8
    日期:1992.12
    2-Hydroxyethyl enol ethers react with Re2O7 to produce 2-hydroxyketals. Where homochiral starting enol ethers are employed, greater than 99:1 diastereoselectivities are obtained. The stereocontrol is rationalized by invoking a transition state that approximates the geometry of a metallaoxetane. Finally, homochiral ketals are themselves oxidized to provide 2-hydroxyketals with high diastereoselectivity
    2-羟乙基烯醇醚与Re 2 O 7反应生成2-羟基缩酮。当使用均手性起始烯醇醚时,获得大于99∶1的非对映选择性。通过调用近似金属氧杂环丁烷的几何形状的过渡态,可以合理地控制立体控制。最后,将手性缩酮本身氧化以提供具有高非对映选择性的2-羟基缩酮。
  • Formation of 2,2-disubstituted 1,3-cyclopentanediones from ketals with 1,2-bis(trimethylsilyloxy)cyclobutene
    作者:Yong-Jin Wu、Dean W. Strickland、Tracy J. Jenkins、Pei-Ying Liu、D. Jean Burnell
    DOI:10.1139/v93-169
    日期:1993.9.1

    The direct formation of 2,2-disubstituted 1,3-cyclopentanedione compounds by a Lewis acid catalysed reaction with 1,2-bis(trimethylsilyloxy)cyclobutene proceeds in good to excellent yields with unhindered ketals, but steric hindrance reduces the yields considerably. A carbonyl group α or β to the ketal, or a carbon–carbon double bond α to the ketal, stops the reaction completely. Orthoesters do not give geminally acylated products in synthetically useful yields.

    通过路易斯酸催化的反应,使用1,2-双(三甲基硅氧基)环丁烯与没有受阻碍的缩酮,直接形成2,2-二取代的1,3-环戊二酮化合物,产率良好至优秀,但立体位阻显著降低了产率。位于缩酮α或β位置的羰基,或者与缩酮α位置相邻的碳-碳双键会完全停止反应。正酯不会以合成有用的产率产生双酰化产物。
  • Optically Pure 3,6-Dioxazocan-2-one Derivatives by Intramolecular Cycloaddition of Azidoformates and their Opening to Substituted α-Amino Ketones
    作者:Marco de Santis、Stefania Fioravanti、Lucio Pellacani、Paolo A. Tardella
    DOI:10.1002/(sici)1099-0690(199911)1999:11<2709::aid-ejoc2709>3.0.co;2-h
    日期:1999.11
    Azidoformates derived from chiral enol ethers, when irradiated, give 3,6-dioxazocan-2-one derivatives 7 by a highly diastereoselective intramolecular cycloaddition. The hydrolysis of 7 gives a single derivative of 2-aminocyclohexanone.
    衍生自手性烯醇醚的叠氮基甲酸酯,经辐射后,会通过高度非对映选择性的分子内环加成反应生成3,6-dioxazocan-2-one衍生物7。7的水解产生2-氨基环己酮的单一衍生物。
