合成路线: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.
