development for the synthesis of ZY12201, a novel TGR5 receptor agonist, as a potential clinical candidate is described. A practical, efficient, and scalable synthetic route provided ZY12201 in seven steps and 32% overall yield. The key step involves an inexpensive acetic acid-mediated cyclization of thiourea 6 for the construction of 2-thio-imidazole derivative 7. The developed process demonstrated cost-effective
描述了用于潜在的临床候选物ZY12201(一种新型TGR5受体激动剂)的合成的早期可扩展方法开发。一条实用,高效且可扩展的合成路线以七个步骤提供了ZY12201,总产率为32%。关键步骤涉及廉价的乙酸介导的硫脲6的环化反应,以构建2-硫代咪唑衍生物7。所开发的工艺证明了ZY12201具有成本效益,高产量,可缩放规模且环保的特点。这种高产途径使我们能够快速合成大量纯度为99%的ZY12201,以支持体内和毒性研究。
