A novel and efficient decarboxylative alkynylation of N-(acetoxy)phthalimides of α-amino acids with terminal alkynes has been developed by merging photoredox with copper catalysis at room temperature, and the reaction provided the valuable propargylamines in good to excellent yields with assistance of [Ru(bpy)3]Cl2/CuI and visible light. The simple protocol, mild reaction conditions, and high efficiency
通过在室温下将光氧化还原与铜催化合并,开发了α-氨基酸的N-(乙酰氧基)邻苯二甲酰亚胺与末端炔烃的新型有效脱羧炔基,该反应在[[]的帮助下,以高至优异的产率提供了有价值的炔丙基胺。 Ru(bpy)3 ] Cl 2 / CuI和可见光。该方法操作简单,反应条件温和且效率高,使其成为合成包含氨基酸片段的多种分子的重要策略。
