An improved process for preparing a 4-mercaptopyrrolidine compound [I]:
wherein R is H, lower alkyl or lower alkanoyl, R¹ is H or SH-protecting group, and X is O or S, which comprises reacting halogenobutyric acid compound [VI], or a salt thereof, with amine compound [VII], or a salt thereof, and if necessary, followed by thiocarbonylating the product and/or removing the protecting group, said 4-mercaptopyrrolidine compound [I] being useful as intermediate for carbapenem antibacterial agents.
制备 4-巯基吡咯烷化合物的改进工艺 [I]:
其中 R 是 H、低级烷基或低级烷酰基,R¹ 是 H 或 SH 保护基,X 是 O 或 S,该工艺包括卤代丁酸化合物[VI]或其盐与胺化合物[VII]或其盐反应,必要时对产物进行硫代羰基化和/或去除保护基,所述 4-巯基吡咯烷化合物[I]可用作碳青霉烯类抗菌剂的中间体。
