The present invention relates to a new process for the preparation of 6-aminopenicillanic acid and 7-amino-cephalosporanic acid derivatives by treating the corresponding acylamino derivatives with phosphinic acid chlorides, reacting the mixed acid anhydrides so obtained with agents forming imidohalides, converting the imido halides into iminoethers and hydrolysing them.
本发明涉及一种新的制备6-氨基青霉烷酸和7-氨基头孢菌素酸衍生物的方法,通过用膦酸氯处理相应的酰胺衍生物,用生成互酸酐的试剂反应所得的混合酸酐,将亚氨基卤代物转化为亚氨基醚并水解它们。
