A protocol for the synthesis of highly substituted 2,4‐diacypryrroles via a copper‐catalyzed ring strain releasing dimerization reaction was developed. The pyrroles are synthesized combining UV–photochemistry and metal‐catalyzed follow up reaction in an one‐pot system. To match the rates of the thermal and the photoinduced step, an internal temperature control was established.
开发了通过铜催化的环应变释放二聚反应合成高度取代的2,4-二酰基吡咯的方案。吡咯是在单锅系统中结合紫外光化学和金属催化的后续反应而合成的。为了匹配热步骤和光引发步骤的速率,建立了内部温度控制。
