  • N-Demethylation of N-methyl alkaloids with ferrocene
    作者:Gaik B. Kok、Peter J. Scammells
    DOI:10.1016/j.bmcl.2010.06.031
    日期:2010.8
    ferrocene has been found to be a convenient and efficient catalyst for the N-demethylation of a number of N-methyl alkaloids such as opiates and tropanes. By judicious choice of solvent, good yields have been obtained for dextromethorphan, codeine methyl ether, and thebaine. The current methodology is also successful for the N-demethylation of morphine, oripavine, and tropane alkaloids, producing the corresponding
    在Polonovski-型条件下,发现二茂铁是一种方便有效的催化剂,可用于许多N-甲基生物碱(如鸦片剂和托烷)的N-脱甲基化。通过明智地选择溶剂,右美沙芬,可待因甲醚和蒂巴因获得了良好的收率。当前的方法学还成功地用于吗啡,奥利巴韦和托烷生物碱的N-去甲基化,以合理的收率生产相应的N -nor化合物。关键的药物中间体,如羟考酮和羟吗啡酮也很容易使用这种方法进行N-去甲基化。
  • An Improved Process for the N-Demethylation of Opiate Alkaloids using an Iron(II) Catalyst in Acetate Buffer
    作者:Gaik Kok、Trent D. Ashton、Peter J. Scammells
    DOI:10.1002/adsc.200800632
    日期:2009.1
    An improved process to N-demethylate opiate alkaloids utilising a solution of the ferrous porphyrin, tetrasodium 5,10,15,20-tetra(4-sulfophenyl)porphyrinatoiron(II) [=Fe(II)-TPPS (8)], in acetate buffer is described. This method provided the corresponding N-demethylated opiates in good yield with high reproducibility.

  • Polonovski-Type N-Demethylation of N-Methyl Alkaloids Using Substituted Ferrocene Redox Catalysts
    作者:Peter Scammells、Gaik Kok
    DOI:10.1055/s-0032-1316590
    日期:2012.8
    Various substituted ferrocenes have been trialed as catalysts in the nonclassical Polonovski reaction for N-demethylation of N-methyl alkaloids. Earlier studies suggest that conditions facilitating a higher ferrocenium ion concentration lead to superior outcomes. In this regard, the bifunctional ferrocene FcCH(2)CO(2)H, with electron donor and acceptor moieties in the same molecule, has been shown to be advantageous for use as a catalyst in the N-demethylation of a number of tertiary N-methylamines such as codeine, thebaine, and oripavine. These substrates are readily N-demethylated under mild conditions, employing sub-stoichiometric amounts of the substituted ferrocene at ambient temperature. These reactions are equally efficient in air and may also be carried out in one pot.
  • New Methodology for the N-Demethylation of Opiate Alkaloids
    作者:Zemin Dong、Peter J. Scammells
    DOI:10.1021/jo071171q
    日期:2007.12.1
    N-Demethylation is a key step in the preparation of a number of semisynthetic opiate pharmaceuticals. Herein we report a high-yielding, catalytic procedure for the N-demethylation of opiates which has a number of advantages over existing methods. For example, tetrasodium 5,10,15,20-tetra(4-sulfophenyl)porphyrinatoiron(II) (0.3 molar equiv) effected the transformation of codeine methyl ether to the corresponding N-nor analogue in 91% yield. The catalyst was readily removed and recycled.
  • Utility of iron nanoparticles and a solution-phase iron species for the N-demethylation of alkaloids

    The N-demethylation of selected N-methylalkaloids using a modified Polonovski reaction can be accomplished using a novel green methodology employing nanoscale zero-valent iron, nZVI, in isopropanol. Use of nZVI promotes a much faster conversion to N-demethylated products due to much higher surface area on the metal surface as shown by SEM analysis. Rates of conversion can be further enhanced using
