合成路线1
该中间体在本合成路线中的序号：(XVI)Cyclization of diazo azetidinone (XIII) by means rhodium(II) octanoate dimer produced the azabicyclo ketone (XIV), which was converted to the phosphorylated carbapenem (XV) employing diphenylphosphorochloridate. Hydrolysis of the thioacetate ester (XII) with NaOMe gave the intermediate thiol (XVI), which was condensed with phosphate (XV) to yield the (pyrrolidinylthio)carbapenem (XVII). Quaternization of the imidazole nucleus of (XVII) with methyl iodide afforded imidazolium salt (XVIII). Then, both allyl ester and allyloxycarbonyl groups of (XVIII) were deprotected using tributyltin hydride and a palladium catalyst. Finally, the iodide salt was exchanged for the corresponding chloride employing an ion exchange resin.
