The protection of 4(R)-hydroxypyrrolidin-2-one (I) first with TBDMS-Cl and then with Boc2O gives the fully protected compound (II), which is condensed with the Grignard reagent of the 4-bromobenzaldehyde dimethyl acetal (III) yielding after working up the substituted benzaldehyde (IV). The reduction of (IV) with NaBH4 affords the benzyl alcohol (V), which is treated with methanesulfonyl chloride to give the corresponding mesylate (VI). The reaction of (VI) with methylamine, followed by protection with Boc2O yields the protected secondary amine (VII), which is desilylated with tetrabutylammonium fluoride to afford the pyrrolidinol (VIII). The reaction of (VIII) with MsCl gives the mesylate (IX), which is treated with potassium thioacetate to provide the acetylsulfanyl derivative (X). The hydrolysis and deprotection of (X) with HCl yields the pyrrolidinethiol (XI), which is condensed with the carbapenem phosphoric ester (XII) to afford the final 4-nitrobenzyl ester intermediate (XIII). Finally, this compound is debenzylated by hydrogenation with H2 over Pd/C.

(R)-4-hydroxy-2-pyrrolidinone (I) was protected as the tert-butyldimethylsilyl ether, and then converted to tert-butyl carbamate (II) by means of Boc2O. Subsequent condensation of (II) with Grignard reagent (III), followed by reduction with NaBH4, and acetal hydrolysis yielded the pyrrolidinyl benzaldehyde (IV). Horner-Emmons reaction of (IV) with phosphonate (V) produced the cinnamic acid derivative (VI), and further Michael addition of the chiral lithium amide (VII) furnished aminoester (VIII). After hydrogenolysis of both N-benzyl groups of (VIII), the resulting primary amine (IX) was protected with Boc2O, and the silyl ether was then cleaved by means of tetrabutylammonium fluoride to give the hydroxypyrrolidine derivative (X). This was converted to the required thiol (XI), which was then coupled with the carbapenem phosphate (XII). Finally, hydrogenolysis of the 4-nitrobenzyl ester of (XII) provided the title compound.

Wittig reaction between aldehyde (I) and methyl(triphenylphosphoranylidene triphenyl)-acetate (II) in refluxing toluene provides E-olefin (III), which is then subjected to reaction with lithium derivative (IV) in THF to afford adduct (V). Benzyl groups of (V) are removed by hydrogenation over Pd(OH)2 in HOAc:MeOH:EtOAc to furnish amine (VI), which is then coupled to Z-Orn(Boc)-OH using 1-ethyl-3-dimethylaminopropylcarbodiimide (WSCD.HCl) and HOBt in CH2Cl2 to give beta-amino acid derivative (VIII). Saponification of the methyl ester group in (VIII) by means of LiOH, followed by condensation with HOBt by means of WSCD.HCl, yields activated ester (IX).
