preparation of [1,2,3,4-13C] testosterone and of [1,2,3,4-13C] estradiol by total synthesis is described. The 13C labels are introduced by alkylating intermediate 1 with [1,2,3,4-13C]l-iodo-3,3-ethylenedioxybutane (2) to obtain intermediate 10. Hydrolysis of the ketal function, cyclization, aromatization and removal of protective groups gave [1,2,3,4-13C] estradiol. Labeled testosterone was prepared by methylating
描述了通过全合成制备[1,2,3,4-13C]睾丸激素和[1,2,3,4-13C]雌二醇。通过用[1,2,3,4-13C] 1-碘-3,3-亚乙基二氧丁烷(2)烷基化中间体1来引入13C标记,以获得中间体10。缩酮功能的水解,环化,芳构化和去除保护基产生[1,2,3,4-13C]雌二醇。通过使中间体10甲基化并随后用酸处理来制备标记的睾丸激素。标记的类固醇可以用作体内代谢研究的示踪剂,也可以用作确定性gc-ms定量方法开发的内部标准。
