6-Amino-spiro[penam-2,4'-piperidine]-3-carboxylic acids, salts and esters thereof of the formula ##STR1## wherein R.sub.1 is hydrogen, benzyl or an alkali metal or ammonium ion and R.sub.2 is methyl, phenyl or benzyl and process for preparing the same. These compounds are useful as intermediates in the synthesis of a new group of antibiotics having properties similar to penicillins, besides own antibiotic activity with a broad antibacterial spectrum. Therefore, they are useful as antibacterials agents and as therapeutic agents for humans and for animals in the treatment of infectious diseases caused by Gram-positive and Gram-negative bacteria.
化合物6-氨基-螺[青霉素-2,4'-哌啶]-3-羧酸及其盐和酯,其化学式为##STR1##
其中R.sub.1为氢,苄基或碱金属或铵离子,R.sub.2为甲基,苯基或苄基,以及其制备方法。这些化合物可用作合成一类具有类似青霉素性质的新型抗生素的中间体,除了具有自身的广谱抗生素活性。因此,它们可用作抗菌剂和治疗人类和动物由革兰氏阳性和革兰氏阴性细菌引起的感染性疾病的治疗剂。
