• Process for producing carbamoyl substituted penams and carbamoyl
  申请人：Bristol-Myers Company

  公开号：US04310459A1

  公开（公告）日：1982-01-12

  Penicillin sulfoxide esters are reacted with an isocyanate to produce the corresponding (substituted)-2-carbamoyloxymethylpenam, the corresponding (substituted)-3-carbamoyloxycepham or the corresponding 3-methylcephem. The 6- or 7-side-chain of these products may be cleaved to give the corresponding 6-amino (penams) or 7-amino (cephams and cephems) compounds, and the latter may be reacylated to produce different 6-acyl-2-carbamoyloxymethyl penams, 7-acyl-3-carbamoyloxy cephams and 7-acyl-3-methylcephems. The substituent groups may be removed from the (substituted-2-carbamoyloxypenams or the (substituted)-3-carbamoyloxycephams to give the corresponding free 2-carbamoyloxymethylpenams or 3-carbamoyloxycephams, respectively.

  盼西林亚砜酯与异氰酸酯反应，生成相应的（取代）-2-氨基羧甲基青霉素，相应的（取代）-3-氨基羧甲氧头孢菌素或相应的3-甲基头孢菌素。这些产物的6-或7-侧链可以被裂解，得到相应的6-氨基（青霉素）或7-氨基（头孢菌素和头孢菌素）化合物，后者可以重新酰化，产生不同的6-酰基-2-氨基羧甲基青霉素，7-酰基-3-氨基羧甲氧头孢菌素和7-酰基-3-甲基头孢菌素。这些取代基团可以从（取代）-2-氨基羧甲氧青霉素或（取代）-3-氨基羧甲氧头孢菌素中去除，分别得到相应的游离2-氨基羧甲基青霉素或3-氨基羧甲氧头孢菌素。
• Nuclear analogs of β-lactam antibiotics. Synthesis of 6,6-disubstituted acylaminopenems

  The preparation of 6α-methyl-2-methyl-6β-phenoxyacetamidopenem-3-carboxylate, 6α-methoxy-2-methyl-6β-phenoxyacetamidopenem-3-carboxylate, and 6α-methoxy-2-methyl-6β-phenylmalonylamidopenem-3-carboxylate from penicillin V and 6-aminopenicillanic acid is described. These penems have been isolated and characterized as their sodium or potassium salt. The chemical stability of the above compounds was determined as their half-life in aqueous buffer. In this way, it was found that the 6α-methyl analog was more stable than the parent 6-monosubstituted acylaminopenem while the remaining analogs were of comparable stability.

  描述了从青霉素V和6-氨基青霉烷酸制备6α-甲基-2-甲基-6β-苯氧乙酰胺基青霉烷-3-羧酸酯、6α-甲氧基-2-甲基-6β-苯氧乙酰胺基青霉烷-3-羧酸酯和6α-甲氧基-2-甲基-6β-苯基丙酰胺基青霉烷-3-羧酸酯的方法。这些青霉烷类化合物已被分离并表征为其钠盐或钾盐。通过在水溶液中测定它们的半衰期，确定了上述化合物的化学稳定性。通过这种方法，发现6α-甲基类似物比亲代6-单取代酰胺基青霉烷更稳定，而其余类似物的稳定性相当。

  Penicillin -cyanosulphoximines are obtained by permanganate oxidation of the sulphilimines. Phthalimidosulphoximines are obtained from penicillin or cephalosporin sulphoxides are phthalimidonitrene (from -aminophthalimide with lead tetraacetate).
