The condensation of azetidinone (I) with carbonate (II) by means of TiCl4 and tributylamine in toluene gives the addition product (III), which is desilylated with HCl in aqueous acetonitrile and resilylated again with Tes-Cl and imidazole in toluene/acetonitrile yielding the silyl ether (IV). The condensation of (IV) with the oxalyl derivative (V) by means of pyridine in toluene affords the addition compound (VI), which is cyclized by means of P(OEt)3 in hot heptane giving the carbapenem compound (VII). The condensation of (VII) with naphthosultam (VIII) by means of palladium acetate and P(OBu)3 affords the protected target compound (IX), which is finally desilylated with aqueous Tf-OH, debenzylated with H2 over Pd/C, and treated with sodium benzenesulfonate to obtain the sulfonate salt of the target compound.
