A novel method to construct the 1-aryl-3-piperidone scaffold is described here. Starting from 3,5-dichloroaniline, a seven-step synthesis, without the use of protecting groups, generates the desired 3-piperidone ring in an overall yield of 30% through a key Morita–Baylis–Hillman reaction and ring-closing metathesis, providing easy access to diverse and useful heterocycles.
这里描述了一种构建 1-芳基-3-哌啶酮支架的新方法。从 3,5-二氯苯胺开始,经过七步合成,不使用保护基团,通过关键的 Morita-Baylis-Hillman 反应和闭环复分解以 30% 的总产率生成所需的 3-哌啶酮环,提供对各种有用的杂环的轻松访问。
