A very efficient method for the preparation of N-acylamino acids from the corresponding acyl chloride and amino acid is described. Amino acids, potassium carbonate, acyl chloride, and a catalytic amount of cationic surfactants were mixed in tetrahydrofuran and refluxed without ever obtaining a clear reaction mixture. After hot filtration, the product was isolated from the hot tetrahydrofuran solution
描述了一种从相应的酰氯和氨基酸制备 N-酰基氨基酸的非常有效的方法。将氨基酸、碳酸钾、酰氯和催化量的阳离子表面活性剂混合在四氢呋喃中并回流,但从未获得澄清的反应混合物。热过滤后,产物以非常高或几乎定量的产率从热的四氢呋喃溶液中分离出来。
