合成路线图解说明:

Treatment of penicillamine (I) with formaldehyde produced thiazolidine (II), which was then protected with Boc2O to give carbamate (III). Coupling of (III) with 2-methylbenzylamine (IV) by means of either diphenylphosphoryl chloride (DPPCl), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide-HCl (EDC) or dicyclohexylcarbodiimide (DCC) afforded the corresponding amide (V). After acid cleavage of the Boc group of (V), the deprotected thiazolidine (VI) was coupled with N-Boc-(S,S)-3-amino-2-hydroxy-4-phenylbutyric acid (VII) using EDC to give diamide (VIII). Further acid deprotection of the Boc group of (VIII) yielded (IX). This was finally coupled with 3-hydroxy-2-methylbenzoic acid (X) to furnish the title compound. Alternatively, amine (IX) was coupled with 3-acetoxy-2-methylbenzoic acid (XI) to afford (XII), which was then deacetylated using NaOH in MeOH.
