A new three‐step synthetic pathway to generate polycyclic annulated hydantoins via rarely investigated heterocyclic imines is described. This procedure includes a one‐pot reaction forming imines as precursor structures (e.g., Asinger reaction), followed by an Ugi reaction to build up a bisamide structure that allows a ring‐closing reaction to the targeted hydantoins via substitution. This pathway leads
描述了一种通过很少研究的杂环亚胺生成多环带环乙内酰脲的新的三步合成途径。此程序包括一锅反应,形成亚胺作为前体结构(例如,Asinger反应),然后进行Ugi反应,以构建双酰胺结构,该双酰胺结构允许通过取代与目标乙内酰脲进行闭环反应。该途径导致具有潜在药理活性的多种物质。
