  A compound of formula (I): 1 wherein R &agr; is hydrogen, optionally substituted (C 1-6 )alkyl or optionally substituted aryl; R &bgr; is hydrogen, optionally substituted (C 1-6 )alkyl or optionally substituted aryl; or R &agr; and R &bgr; together form an optionally substituted 5 or 6 membered heterocyclic ring with or without additional heteroatoms; R 1 is (C 1-6 )alkyl which is unsubstituted or substituted by fluoro, a hydroxy group which is optionally protected by a removable hydroxy protecting group, or by an amino group which is optionally protected by a removable amino protecting group; R 2 is hydrogen or methyl; and —CO 2 R 3 is carboxy or a carboxylate anion or the group R 3 is a removable carboxy protecting group. This invention also relates to processes for its preparation, intermediates and pharmaceutical compositions comprising compounds of formula (I). Compounds of formula (I) which include pharmaceutically acceptable salts or pharmaceutically acceptable in vivo hydrolysable esters thereof have a broad spectrum of anti-bacterial activity and show good stability towards DHP-1.

  式(I)的化合物：其中R&agr;为氢，可选地取代的（C1-6）烷基或可选地取代的芳基；R&bgr;为氢，可选地取代的（C1-6）烷基或可选地取代的芳基；或R&agr;和R&bgr;共同形成一个可选地取代的5或6元杂环环，带或不带额外的杂原子；R1为（C1-6）烷基，未取代或由氟取代，或者是可选地由可拆卸的羟基保护基保护的羟基基团，或者是可选地由可拆卸的氨基保护基保护的氨基基团；R2为氢或甲基；和-CO2R3为羧基或羧酸根离子，或者基团R3为可拆卸的羧基保护基。本发明还涉及其制备方法、中间体和包括式(I)化合物的制药组合物。式(I)的化合物包括其药学上可接受的盐或药学上可在体内水解的酯，具有广谱的抗菌活性，并对DHP-1表现出良好的稳定性。
