摘要: 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.
