A pyrrolidylthiocarbapenem derivative represented by Formula I is provided:
wherein R¹ is hydrogen or lower alkyl; R², R³ and R⁴ are hydrogen, lower alkyl which can be substituted or an amino protecting group independently, or R² and R³ together with a nitrogen atom to which R² and R³ are bonded form a saturated or unsaturated cyclic group, or R²and R⁴, or R³ and R⁴ together with two nitrogen atoms and one sulfur atom in the sufamide group form a saturated or unsaturated cyclic group; each cyclic group can further include at least one atom selected from the group consisting of oxygen, sulfur and nitrogen, and each cyclic group can be substituted; X¹ is hydrogen or a hydroxy protecting group; X² is hydrogen, a carboxy protecting group, an ammonio group, an alkali metal or an alkaline-earth metal; and Y² is hydrogen or an amino protecting group.
提供了一种由式 I 代表的吡咯烷基硫代碳青霉烯类衍生物:
其中 R¹ 为氢或低级烷基;R²、R³ 和 R⁴ 分别为氢、可被取代的低级烷基或氨基保护基团,或 R² 和 R³ 与 R² 和 R³ 键合的一个氮原子一起形成饱和或不饱和环状基团,或 R² 和 R⁴,或 R³ 和 R⁴ 与 sufamide 基团中的两个氮原子和一个硫原子一起形成饱和或不饱和环状基团;每个环状基团可进一步包括至少一个选自氧、硫和氮组成的原子,且每个环状基团可被取代;X¹为氢或羟基保护基团;X²为氢、羧基保护基团、氨基、碱金属或碱土金属;Y²为氢或氨基保护基团。
