    名称:
    Enantioseparation of racemic organic ammonium perchlorates by a silica gel bound optically active di-tert-butylpyridino-18-crown-6 ligand
    摘要:
    Both enantiomers of the novel chiral di-tert-butylpyridino-18-crown-6 ligand (R,R)-7 and (S,S)-7 containing an allyloxy group on the pyridine subcyclic unit were prepared by the reaction of 4-allyloxy-2,6-pyridinedimethyl ditosylate 9 and the enantiomers of di-tert-butyl-substituted tetraethylene glycol (R,R)-8 and (S,S)-8 in the presence of a strong base. One of them, (R,R)-7, was covalently attached to silica gel, and this chiral stationary phase (CSP) separated four selected racemic organic ammonium perchlorates into their enantiomers by column chromatography.

  • Bromination of Enamines from Tertiary Amides Using the Petasis Reagent: A Convenient One-Pot Regioselective Route to Bromomethyl Ketones
    作者:Marwan Kobeissi、Khalil Cherry、Wissam Jomaa

    bromomethyl ketones is achived using the Petasis reagent (dimethyltitanocene) as a key for enamine generation. Several amides were used to test the limits of the procedure by changing either the alkyl chain R or the amino portion of the starting materials. The enamines generated in situ were allowed to react with bromine at low temperature followed by hydrolysis to yield bromomethyl ketones in excellent
    摘要 使用 Petasis 试剂(二甲基二茂钛)作为烯胺生成的关键,实现了溴甲基酮的原始一锅法合成。通过改变烷基链 R 或起始材料的氨基部分,使用几种酰胺来测试该程序的限制。使原位生成的烯胺在低温下与溴反应,然后水解,以极好的收率(85% 至 95%)得到溴甲基酮。简要讨论了反应的机理细节和最佳条件。本方法提供了几个优点,例如烯胺形成的区域选择性、良好的产率、温和的反应条件和易于实验。[本文提供补充材料。去出版商'

    The exchange reaction of α-mercurated ketones with bis(triethylsilyl)- (I) and bis(triethylgermyl)mercury (II) leads to the formation of the corresponding triethylsilyl and triethylgermyl enol ethers. O-Silylated and O-germylated enolates derived from ketones and aldehydes can be also prepared by treating mercurials I and II with appropriate α-bromo-carbonyl compounds. This new pathway also represents
