Selective formation of amides or peptides with ethanol as solvent using a convenient one-pot procedure in which acid activating agent N-(3-dimethylaminopropyl)-N-ethylcarbodiimide hydrochloride (EDC) is simply added to a mixture of the carboxylic acid, amine, catalytic HOBt (1-hydroxy benzotriazole), and NMM (N-methylmorpholine) as base has been developed. Sensitive functionalities such as hydroxyl
使用方便的一锅法,以乙醇为溶剂选择性地形成酰胺或肽,其中将酸活化剂N-(3-二甲基氨基丙基)-N-乙基碳二亚胺盐酸盐(EDC)简单地添加到羧酸,胺,已经开发出了催化的HOBt(1-羟基苯并三唑)和NMM(N-甲基吗啉)作为碱。在反应条件下,对羟基等敏感官能团的耐受性良好。另外,通常通过从反应介质中简单过滤来分离产物。研究了这种方法的范围和一般性。
