four more steps, respectively. For the radioactive synthesis, potassium cyanide-(14) C was used to prepare 1-cylobutylaminoacid [(14) C]-(23) via Buchrer-Bergs reaction. The carbonyl chloride of this acid was then used to access both [(14) C]-(1) and [(14) C]-(2) in four steps. The acyl glucuronide derivatives [(13) C6 ]-(3), [(13) C6 ]-(4) and [(14) C]-(3) were synthesized in three steps from the acids
Deleobuvir, (2E)-3-(2-1-[2-(5-bromopyrimidin-2-yl)-3-cyclopentyl-1-methyl-1H-indole-6-carboxamido]
环丁基}-1-methyl- 1H-benzimidazol-6-yl)prop-2-enoic acid (1) 是一种非核苷的、有效的、选择性的丙型肝炎病毒 NS5B 聚合酶
抑制剂。在这里,我们描述了这种用碳 13 和碳 14 标记的化合物的详细合成。还报道了其三种主要代谢物的合成,即还原的双键代谢物 (2) 和 (1) 和 (2) 的酰基
