该中间体在本合成路线中的序号：(XVIII)The reaction of 4(R)-hydroxy-L-proline (I) with allyl chloroformate (II) and NaOH gives the protected proline (III), which is esterified with MeOH and sulfuric acid to yield the methyl prolinate (IV). The reaction of (IV) with Ms-Cl and TEA affords the mesylate (V), which is reduced with NaBH4 to provide the prolinol derivative (VI). The Swern oxidation of alcohol (VI) gives the carbaldehyde (VII), which is condensed with the phosphorane (VIII) by means of NaOMe, yielding the acrylate (IX). The reduction of (IX) with DIBAL affords the substituted allyl alcohol (X), which is condensed with phthalimide (XI) by means of PPh3 and DIAD to provide the adduct (XII). The cleavage of the phthalimido group of (XII) with hydrazine gives the amino derivative (XIII), which is treated with Ms-Cl and TEA to yield the sulfonamide (XIV). The reaction of (XIV) with potassium thioacetate affords the acetylsulfanyl pyrrolidine (XV), which is hydrolyzed with HCl to provide the thiol (XVI). The condensation of the thiol (XVI) with the carbapenem derivative (XVII) by means of DIEA gives the protected adduct (XVIII), which is finally treated with Pd(II) and Bu3SnH in order to eliminate the allyl protecting groups. The intermediate carbapenem derivative (XVII) has been obtained from azetidinone (XIX) by known methods as indicated in the scheme.
