The 2-(hydroxymethyl)penem (I) is transformed into the corresponding mesylate (II), which is then condensed with sarcosinamide (III), to afford adduct (IV). The O-silyl group of (IV) is removed by treatment with tetrabutylammonium fluoride, yielding alcohol (V). Finally, the allyl ester group of (V) is cleaved in the presence of palladium and triphenylphosphine to furnish the target carboxylic acid.

In a related method, the 4-acetoxy-azetidinone (I) is reacted with 2-chlorothioacetic acid (II) in the presence of ZnI2 to give the (chloroacetylthio)azetidinone (III). Nitrogen acylation in (III) by means of allyl oxalyl chloride produces (IV), which undergoes ring closure to the penem (V) in the presence of triethyl phosphite in boiling toluene. Displacement of chloride (V) with sarcosinamide (VI) yields adduct (VII). After desilylation of (VII) to (VIII) by means of tetrabutylammonium fluoride, palladium-catalyzed allyl ester cleavage leads to the title compound.

The condensation of N-(2-chloroethyl)-N-nitrosocarbamic acid 4-nitrophenyl ester (I) with sarcosinamide (II) gives the target nitrosourea. Alternatively, the nitrosation of N2-[N-(2-chloroethyl)carbamoyl]sarcosinamide (III) by means of NaNO2 and formic acid also yields the target nitrosourea.

ZK-807834 is obtained by condensation of the diaryl ether (I) with the phenol (II) by means of K2CO3 to afford the bisaryl ether (III). Reaction of the cyano group of (III), first with HCl in ethanol and then with ammonia, yields the corresponding amidino compound (IV), which is finally demethylated with HBr.
