    摘要: This invention concerns 2-amido-6-aminopenicillanic acids, 2amido-6-haloimidopenicillins, 2-amido-6-alkoxyimidopenicillins, 2-amido-7-aminocephalosporanic acids, 2-amido-7haloimidocephalosporins and 2-amido-7-alkoxyimidocephalosporins which are useful as intermediates in the preparation of synthetic penicillins and cephalosporins having potent antibiotic activity. Further, it relates to a process for the preparation of these intermediates from penicillins and cephalosporins. Still further, it concerns the preparation of 6-aminopenicillanic acid and 7aminocephalosporanic acid by the respective hydrolysis of 2amido-6-aminopenicillanic acids and 2-amido-7aminocephalosporanic acids.
