A general selective and environmentally friendly method for the formation of amide bonds using a surfactant in water as medium is described. The use of readily available 1-ethyl-3-(3-(dimethylamino)propyl)carbodiimide (EDC) and hydroxybenzotriazol (HOBt) as a coupling system, N-methylmorpholine (NMM), and TPGS-750-M represents mild conditions allowing for chemoselective amidation of unprotected amino
描述了使用表面活性剂在水中作为介质来形成酰胺键的一般选择性和环境友好的方法。使用现成的1-乙基-3-(3-(二甲基氨基)丙基)碳二亚胺(EDC)和羟基苯并三唑(HOBt)作为偶联体系,N-甲基吗啉(NMM)和TPGS-750-M代表温和的条件,允许用于未保护的氨基醇的化学选择性酰胺化。给出了与经典极性非质子溶剂(如二甲基甲酰胺或乙腈)的比较结果。
