  • Nitroaldol reaction of nitro[11C]methane to form 2-(hydroxymethyl)-2-nitro[2-11C]propane-1,3-diol and [11C]Tris

    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-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.
