合成路线1
该中间体在本合成路线中的序号：(XIII)1,2-Dideoxy-D-ribose (IX) was converted to bismesylate (X) upon treatment with methanesulfonyl chloride and pyridine. Displacement of the primary mesylate group of (X) with LiN3 in DMF gave azide (XI). The secondary mesylate group was further displaced with potassium thioacetate to provide (XII). Thiol (XIII) was then prepared by hydrolysis of the thioester function with NaOMe in THF.

合成路线2
该中间体在本合成路线中的序号：(XIII)In an alternative procedure, deoxyribose (XIV) was reduced to 2-deoxy-D-erythropentitol (XV) with NaBH4. Acid-catalyzed cyclization of (XV) produced (IX), which was converted to triflate (XVI) using trifluoromethanesulfonic anhydride and pyridine. Displacement with tetrabutylammonium azide provided azido derivative (XVII). Further treatment with trifluoromethanesulfonic anhydride gave triflate (XVIII), which was then displaced with potassium thioacetate to yield thioester (XII). This was hydrolyzed with NaOMe as above to furnish thiol (XIII).

合成路线3
该中间体在本合成路线中的序号：(XIII)Coupling of carbapenem phosphate (VIII) with thiol (XIII) using diisopropylethylamine gave rise to sulfide (XIX). Hydrogenolysis of the p-nitrobenzyl group of (XIX) with simultaneous azide reduction in the presence of Pd/C provided (XX). Treatment of p-nitrobenzyl chloroformate (XXI) with p-nitrophenol (XXII) afforded the nitrophenyl carbonate (XXIII), which was coupled with L-valine (XXIV), yielding carbamate (XXV). Activation of (XXV) with N-hydroxy succinimide and DCC then produced the succinimidyl ester (XXVI). Amine (XX) was coupled with succinimidyl ester (XXVI) to furnish amide (XXVII). The p-nitrobenzyl ester was finally removed by hydrogenation over Pd/C to provide the title compound.
