1-Sulfo-2-oxoazetidine derivatives represented by the formula (I)
wherein R, stands for an amino group which may optionally be acylated or protected, and X stands for hydrogen or methoxy, is produced by subjected a 1-t-butyl or isopropylsilyl derivative of a compound represented by the formula (II)
wherein R2 stands for an amino group which is acylated or protected, and X is of the same meaning as defined above, to sulfonation, followed by, when R2 is a protected amino group, removing the protective group, if necessary.
The compounds represented by the formula (I) have an excellent antibacterial and β-lactamase-inhibitory activity, thus being useful as drugs for humans and domestic animals.
由式(I)表示的 1-磺基-2-氧代氮杂环丁烷衍生物
将式(II)所代表化合物的 1-叔丁基或异丙基硅烷衍生物,其中 R2 代表可选择酰化或保护的氨基,X 代表氢或甲氧基,进行硫化而制得。
其中 R2 代表酰化或受保护的氨基,X 的含义与上述定义相同。
式 (I) 所代表的化合物具有优异的抗菌和抑制 β-内酰胺酶活性,因此可作为人类和家畜的药物。
