A fast and convenient microwave assisted one-pot synthesis of methyl-[14C]-isothiocyanate 4 was shown. The continued one-pot synthesis with 4 to a highly refined material like [5-14C]-dimethylsulfanyltriazolepyridines 8 and 13 without any intermediate purification, six steps in the same pot from [14C]KCN. Oxidation of the sulfur provided access to triazole-ethers upon reaction with alcohols. The triazole-ethers, 15, were obtained at fair to good yields and specific activities above 2 GBq/mmol.

研究人员展示了一种快速、便捷的微波辅助一步法合成甲基-[14C]-异硫氰酸酯 4 的方法。在同一锅中,从[14C]KCN 经过六个步骤,将 4 与[5-14C]-二甲基硫基三唑吡啶 8 和 13 等高纯度材料继续进行单锅合成,而无需进行任何中间纯化。在与醇反应时,硫的氧化作用提供了获得三唑醚的途径。获得的三唑醚类化合物 15 产率尚可,比活度超过 2 GBq/mmol。Copyright © 2008 John Wiley & Sons, Ltd. All Rights Reserved.
