Abstract A microwave-assisted montmorillonite K-10 catalyzed synthesis of pyrrolocoumarins and pyrroloquinolones from acetylenic amine is described. The reaction utilizes montmorillonite K-10 as an inexpensive, recyclable, and environmentally benign acid catalyst. Reactions were completed in few minutes under microwave irradiation and provided excellent yields. The efficient and eco-friendly catalyst
摘要 描述了微波辅助的蒙脱石K-10从炔属胺合成吡咯香豆素和吡咯并喹诺酮。该反应利用蒙脱石K-10作为廉价,可回收和环境友好的酸性催化剂。反应在微波辐射下在几分钟内完成,并提供优异的收率。高效,环保的催化剂以及产物分离的便利性使该方法成为合成这些重要杂环的有吸引力的替代方法。 描述了微波辅助的蒙脱石K-10从炔属胺合成吡咯香豆素和吡咯并喹诺酮。该反应利用蒙脱石K-10作为廉价,可回收和环境友好的酸性催化剂。反应在微波辐射下在几分钟内完成,并提供优异的收率。高效,环保的催化剂以及产物分离的便利性使该方法成为合成这些重要杂环的有吸引力的替代方法。
