employing 2-trimethylsiloxy-1,3-butadiene, a reduction step was avoided, thus providing rapid entry into the piperidine core structure. This protocol led to the synthesis of some racemic 2-aminomethyl-4-oxo-piperidines; intermediates that were synthesized in multigram quantities.
摘要 通过 3 组分杂 Diels-Alder 反应实现了对 2-取代哌啶核的轻松访问。适当官能化的亚胺的使用允许在一个步骤中为哌啶和2-位侧链氮安装保护基团。此外,通过使用 2-三甲基甲硅烷氧基-1,3-丁二烯,避免了还原步骤,从而快速进入哌啶核心结构。该方案导致合成了一些外消旋 2-aminomethyl-4-oxo-piperidines;以数克数量合成的中间体。
