The feasibility of an amidation method for a general synthesis of industrially important semi‐synthetic cephalosporin antibiotics starting from readily available 7‐aminocephalosporanic acid and derivatives thereof is demonstrated. The amidation process is based on the use of 4‐toluenesulfonyl chloride as an economically attractive coupling reagent in combination with methanol or ethyl acetate as preferred
从现有的7-氨基头孢烷酸及其衍生物开始,证明了酰胺化方法用于一般合成工业上重要的半合成头孢菌素抗生素的可行性。酰胺化过程基于使用4-甲苯磺酰氯作为经济上有吸引力的偶联剂,并与甲醇或乙酸乙酯作为优选的溶剂组分组合使用。
