a green, expeditious, and practically simple protocol for direct coupling of carboxylate salts and ammonium salts under ACN/H2O conditions at room temperature without the addition of tertiary amine bases. The water-soluble coupling reagent EDC·HCl is a key component in the reaction. The reaction runs smoothly with unsubstituted/substituted ammonium salts and provides a clean product without column
在此,我们报告了一种绿色、快速且实际简单的方案,用于在室温下在 ACN/H 2 O 条件下直接偶联羧酸盐和铵盐,而无需添加叔胺碱。水溶性偶联剂EDC·HCl是反应中的关键组分。使用未取代/取代的铵盐,反应顺利进行,无需柱层析即可提供干净的产品。我们的反应耐受羧酸盐(以其他形式不稳定)和胺盐(以游离形式存在时不稳定/易挥发)。我们相信所报道的方法可以用作实验室和工业规模的替代和合适的方法。
