合成路线图解说明: The condensation of 2-bromo-4-nitrotoluene (I) with phenylboronic acid (II) by means of Pd(OAc)2 in aqueous acetone gives the biphenyl (III), which is oxidized with KMnO4 in aqueous pyridine yielding the biphenyl-2-carboxylic acid (IV). The condensation of (IV) with L-methionine methyl ester (V) by means of EDC and HOBT affords the amide (VI), which is reduced with SnCl2 to give the 5-aminobiphenyl derivative (VII). The reductocondensation of (VII) with N-(tert-butoxycarbonyl)-S-trityl-L-cysteinal (VIII) by means of NaBH3CN affords the secondary amine (IX), which is finally deprotected with HgCl2 and H2S in methanol to furnish the target ester.
