    摘要:
    该论文描述了首个用于对具备进一步衍生化活性基团的苯环类化合物进行n.c.a 11C-环标记的方法,该方法利用已知的六电子环化将己三烯系统同步转化为芳香族化合物的原理。由回旋加速器产生的[11C]二氧化碳制备的硝基[11C]甲烷(1),在叔丁基钾的存在下与5-二甲氨基戊-2,4-二烯基二甲基铵高氯酸盐(2)反应,形成6-硝基-1-二甲氨基[6-11C]己三烯(3),随后在升温条件下环化/芳香化成硝基[1-11C]苯(4)。从1开始,在7分钟内获得了放射化学纯度约为92%、平均比放射性为1 Ci/μmol的硝基[1-11C]苯。相对于[11C]CO2,4的可重复放射化学产率(衰变校正)为80±5%。通过在上述反应混合物中加热与水溶液Na2S反应,将4还原,得到放射化学纯度约为81%的[1-11C]苯胺(5)。相对于[11C]CO2,5的可重复放射化学产率(衰变校正)为65±5%,从1开始的合成时间为18分钟。

  • N.C.A. 11C-labelling of benzenoid compounds in ring positions: Synthesis of nitro-[1-11C]benzene and [1-11C]aniline
    作者:J. Steinbach、P. Mäding、F. Füchtner、B. Johannsen

    The paper describes the first method for n.c.a 11C-ring labelling of benzenioid compounds having a reactive group for further derivatization by use of the known principle of synchronous six-electron cyclization of hexatriene systems into aromatics. Nitro-[11C]methane (1) prepared from cyclotron-produced [11C]carbon dioxide reacts in the presence of t-BuOK with 5-dimethylaminopenta-2,4-dienylidene-dimethylammonium perchlorate (2) to form 6-nitro-1-dimethylamino-[6-11C]hexatriene (3) follow by cyclization/ aromatization into nitro-[1-11C]-benzene (4) at increased temperatures. Starting from 1, nitro-[1-11C]benzene of a radiochemical purity of about 92 % and a mean specific radioactivity of 1 Ci/μmol was obtained within 7 min. Related to [11C]CO2, the reproducible radiochemical yield of 4 (decay-corrected) was 80±5 %. Reduction of 4 by heating the above reaction mixture with aqueous Na2S gave [1-11C]aniline (5) of aradiochemical purity of about 81 %. The reproducible radiochemical yield of 5 (decay-corrected) in relation to [11C]CO2 was 65±5 %, the synthesis time from 1 was 18 min.

    The nitroaldol reaction of nitro[11C]methane and formaldehyde, which yields 2-(hydroxymethyl)-2-nitro[2-11C]propane-1,3-diol, is explored. The fluoride-ion-assisted nitroaldol reaction using (C4H9)4NF was rapid and provided the desired nitrotriol in more than 97% radiochemical conversion (decay-corrected) in 3 min at room temperature. Neither 2-nitro[2-11C]ethanol nor 2-nitro[2-11C]propane-1,3-diol was observed under the reaction conditions. The preparation of 2-amino-2-(hydroxymethyl)-[2-11C]propane-1,3-diol ([11C]Tris) was described, which was followed by the nitro-group reduction using NiCl2 and NaBH4 in aqueous MeOH. The decay-corrected radiochemical conversion to [11C]Tris was 68.0±6.5% in two steps. Copyright © 2010 John Wiley & Sons, Ltd.
    对硝基[11C]甲烷和甲醛的硝基阿尔多反应进行了探讨,生成2-(羟甲基)-2-硝基[2-11C]丙烷-1,3-二醇。采用(C4H9)4NF辅助的氟离子硝基阿尔多反应快速进行,在室温下3分钟内实现了超过97%的放射化学转化(衰变校正)并获得了所需的硝基三醇。在反应条件下未观察到2-硝基[2-11C]乙醇或2-硝基[2-11C]丙烷-1,3-二醇。描述了2-氨基-2-(羟甲基)-[2-11C]丙烷-1,3-二醇([11C]Tris)的制备,随后进行了硝基的还原,采用NiCl2和NaBH4在水醇中进行。经过两步反应,衰变校正的放射化学转化率为68.0±6.5%至[11C]Tris。版权©2010 John Wiley & Sons, Ltd.
  • Purification of [<sup>11</sup>C]nitromethane for use in asymmetric nitroaldol reactions
    作者:Sven Åke Gustavsson、Koichi Kato、Bengt Långström
    DOI:10.1002/jlcr.787
    日期:2003.12
    [11C]Nitromethane was prepared by modifying previously published procedures. Nitrogen oxides contaminating the [11C]nitromethane were removed by a heated sodium carbonate plug. An asymmetric nitroaldol reaction was performed using a lanthanum–lithium–(R)-binol (LLB) complex as catalyst. 1-Nitro-4-phenylbutan-2-ol was produced in a reaction between [11C]nitromethane and 3-phenyl-propionaldehyde in 16% enantiomeric excess (e.e.) and a radiochemical yield of 23%.

    [11C]硝基甲烷是通过修改以前公布的程序制备的。用加热的碳酸钠塞去除污染[11C]硝基甲烷的氮氧化物。使用镧-锂-(R)-binol (LLB) 复合物作为催化剂,进行了不对称硝基甲醇反应。在[11C]硝基甲烷和 3-苯基丙醛的反应中生成了 1-硝基-4-苯基丁-2-醇,对映体过量率为 16%,放射化学收率为 23%。Copyright © 2003 John Wiley & Sons, Ltd. All Rights Reserved.
