not commercially available. Reported approaches for the synthesis of T0, 3,5-T2, TA3 and TA4 lack sensitivity and/or are not adaptable for 13C6-labeled analogues. In this paper, we describe the synthesis of four 13C6-labeled THMs, T0-13C6, 3,5-T2-13C6, TA3-13C6, TA4-13C6. Starting with 13C6-bromo-benzene, a short and versatile synthesis route was developed in which the formation of the diphenyl ether
T3,rT3和T4以外的甲状腺激素代谢物(THMs)的作用很大程度上未知,部分原因是缺乏适当的方法。为了进行适当的分析,所有THM的内部标准都是必不可少的,但不幸的是,该标准没有市售。报道的合成T 0,3,5-T 2,TA 3和TA 4的方法缺乏敏感性和/或不适用于13 C 6标记的类似物。在本文中,我们描述了四个合成13 Ç 6 -标记的三卤甲烷,T0- 13 Ç 6,3,5- T2- 13 Ç 6,TA3- 13 Ç 6,TA4- 13 Ç 6。从13开始C 6-溴苯,开发了一种短而通用的合成路线,其中通过Chan-Lam偶联反应形成二苯醚是基础。
