    • A penem derivative represented by the following formula (I):
      wherein R 1 represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted alkylthio group, a substituted or unsubstituted alkenylthio group, a substituted or unsubstituted aralkylthio group, a substituted or unsubstituted arylthio group, a substituted or unsubstituted heterocyclic group, a substituted or unsubstituted heterocyclic thio group, a substituted or unsubstituted acylthio group, a mercapto group or a hydrogen atom, and R 2 represents a hydrogen atom or a carboxyl-protecting group; or a pharmacologically acceptable salt thereof.
      The compound (I) exhibits strong antibacterial activities, and especially, shows strong activities against MRSA. It is therefore useful not only as a general antibacterial agent but also as an antibacterial agent for MRSA against which no general antibacterial agents are recognized to be effective.
    • 由下式(I)表示的pen嗪衍生物:其中R 1表示取代或未取代的烷基,取代或未取代的烯基,取代或未取代的芳烷基,取代或未取代的芳基,取代或未取代的芳基 取代或未取代的芳硫基,取代或未取代的芳硫基,取代或未取代的杂环基,取代或未取代的杂环硫基,取代或未取代的酰硫基,巯基或巯基 氢原子,R 2表示氢原子或羧基保护基; 或其药理学上可接受的盐。 化合物(I)表现出强烈的抗菌活性,特别是对MRSA具有强烈的活性。 因此,不仅可以作为普通抗菌剂,而且作为MRSA的抗菌剂也是有用的,因为没有一般的抗菌剂被认为是有效的。

    • The invention relates to a process for synthesizing a 4-substituted azetidinone derivative represented by the general formula (3) (wherein OR₁ represents a protected hydroxyl group; CO₂R₃ represents an esterified carboxyl group; and X and Y represent each independently alkyl, alkenyl, aralkyl, aryl, alkylthio, alkoxy, heterocycle, acyl, amino, hydrogen or halogen, or alternatively X and Y are combined together to represent cycloalkan-2-on-2-yl) by the reaction of an azetidinone derivative represented by general formula (1) (wherein OR₁ is as defined above; and R₂ represents alkyl, alkenyl or aryl) with an ester compound represented by general formula (2): (wherein CO₂R₃, X and Y are each as defined above) in the presence of zinc and copper compounds. The invention relates also to a compound represented by general formula (3) and further to a compound prepared by decarboxylating the compound (3), both being useful as an intermediate for synthesizing antibacterial carbapenem compounds.
    • 本发明涉及由通式(3)表示的4-取代氮杂环丁酮衍生物的合成方法(式中OR 1代表被保护的羟基; CO 2 R 3代表酯化的羧基; X和Y分别独立地代表烷基,链烯基,芳烷基 (1)所示的氮杂环丁酮衍生物与式(1)所示的氮杂环丁酮衍生物反应,从而得到式(1)所示的环烷基-2-酮基 )(其中OR 1定义如上; R 2代表烷基,链烯基或芳基)与通式(2)代表的酯化合物反应:(其中CO 2 R 3,X和Y的定义同上)在锌和铜 化合物。 本发明还涉及由通式(3)表示的化合物,还涉及通过使化合物(3)脱羧而制备的化合物,两者都可用作用于合成抗菌碳杂青霉烯化合物的中间体。
