合成路线1
该中间体在本合成路线中的序号：(IX)L-Tartaric acid (I) was converted to succinimimide (II) upon treatment with benzylamine in refluxing xylene with azeotropic removal of water. Subsequent reduction of (II) with borane, generated from NaBH4 and BF3, afforded pyrrolidine (III). Removal of the N-benzyl group of (III) was effected by hydrogenolysis over Pd/C, and the resulting secondary amine (IV) was coupled with the N-protected 3-thioacetylproline (V) to furnish amide (VI). Deacetylation of (VI) under basic conditions provided thiol (VII). Condensation of thiol (VII) with carbapenem enolphosphate (VIII) afforded thioether (IX). The 4-nitrobenzyl protecting groups of (IX) were finally removed by hydrogenolysis over Pd/C.
