  一种JAK抑制剂的合成方法

  摘要：

  本发明公开了一种JAK抑制剂的合成方法，包括：将中间体A‑8和中间体B‑3缩合得到中间体AB‑1，中间体AB‑1经过去保护后得到中间体AB‑2,AB‑2环合后得到中间体AB‑3，AB‑3去保护得到中间体AB‑4，AB‑4再次去保护中间体AB‑5，AB‑5经过缩合反应得到JAK抑制剂1。本发明的优点主要体现在：以手性催化的方法高产率和高手性纯度制备中间体A‑8、高产率得到中间体B‑3及JAK抑制剂1。几乎杜绝了无用对映体的产生，减少了环境的压力，同时反应产率高，操作简单，后处理简便。本发明的反应条件也能应用于大量制备，适合工业化生产，因而具有较高的实用价值和社会经济效益。
