The following two isomers exist in this carbapenem skeleton. Among these, carbapenem derivatives with β coordination have much higher antibacterial activity, and all carbapenem antibacterial agents currently under development, including thienamycin, have this coordination. Therefore,
As an intermediate, it is desirable to have a coordination that can induce this β-coordination carbapenem, but chemically synthesized 4-substituted azetidine-
It has been difficult to obtain only the 2-one derivative easily and in high yield. The present inventors have discovered that a 4-substituted azetidin-2-one derivative having the specific coordination can be easily obtained by using the compound of the present invention, and have completed the present invention. Therefore, an object of the present invention is to provide a novel pyridine derivative having optical activity useful as an intermediate for antibacterial agents and a method for producing the same.
