PROCESS FOR PRODUCING NEW OXIME DERIVATIVES OF 3-THIADIAZOLYTHIO-METHYL-7-AMINOTHIAZOLYLACETAMIDO-CEPH-3-EME-4-CARBOXYLIC ACIDS |
摘要 |
<p>The compounds correspond to the formula: <IMAGE> in which R1 represents hydrogen or certain protective groups, R2 represents certain alkyl radicals, R3 represents C1-C4 alkyl or alkoxy radicals and A represents hydrogen, an alkali metal, alkaline-earth metal, magnesium or amine cation or an ester group; the preferred compounds have the syn configuration. The preparation is carried out by creating the amide bond from the carboxyl component and the substituted 7-aminocephem component, followed by an acid hydrolysis, a hydrogenolysis or a treatment with thiourea when it is desired to remove the protective groups R1 and A. The compounds are active with respect to gram (+) and (-) bacteri; they can be used in the treatment of relevant infections.</p> |
