合成路线1
The dipeptide intermediate (XI) has been obtained as follows: The coupling of the two synthons (I) and (II) by means of K2CO3 and 18-C-6 in DMSO gives the diphenyl ether (III), which is reduced at its nitro group with H2 over Pd/C yielding the amine (IV). The treatment of (IV) with tert-butyl nitrite, HBF4 and Cu2O affords the phenol (V), which is methylated with MeI and K2CO3 to provide the corresponding methyl ether (VI). The protection of the primary alcohol of (VI) with benzyl bromide (A) and K2CO3 gives the benzyl ether (VII), which is deprotected at the Mem and trifluoroacetamido groups yielding the aminoethanol derivative (VIII). The condensation of (VIII) with the protected phenylalanine derivative (IX) by means of EDC and HOBT affords the corresponding amide (X), which is finally oxidized with Dess Martin periodinane (DMP) and NaClO2 to afford the desired dipeptide intermediate (XI).

The synthesis of intermediate (XI) as been performed as follows: The reaction of 3-benzyloxy-5-methoxystyrene (I) with K2OsO4(OH)4, (DHQ)2PHAL and BocNClNa gives the hydroxyethyl carbamate (II), which is protected with Mem-Cl, yielding (III). The reductive deprotection of (III) with H2 over Pd/C, followed by reaction with trifluoroacetic anhydride (TFAA), affords the amide (IV), which is condensed with the hydroxyethyl carbamate (V) (obtained by reaction of 3-fluoro-4-nitrostyrene (VI) with K2OsO4(OH)4, (DHQD)2PHAL and BocNClNa) by means of K2CO3, providing the diaryl ether (VII). The reduction of the nitro group of (VII) with H2 over Pd/C gives the corresponding amino group, which is converted into the phenol (IX) by reaction with tBu-ONO, BHF4, Cu2O and Cu(NO3)2. The methylation of the phenol (IX) with MeI and K2CO3 yields the corresponding ether (X), which is finally treated with K2CO3 to eliminate the trifluoroacetyl group, yielding the desired intermediate (XI).

The synthesis of intermediate (XXI) has been performed as follows: The condensation of 4-fluoro-3-nitrobenzyl bromide (XII) with the chiral dihydropyrazine (XIII) by means of BuLi and CuCN gives the chiral adduct (XIV), which is treated with TFA to yield the 4-fluoro-3-nitro-D- phenylalanine (XV). The N-protection of (XV) with Teoc-Cl gives the N-protected phenylalanine (XVI), which is condensed with the already described intermediate (XI) by means of PyBop to yield the amide (XVII). The oxidation of the primary OH group of (XVII) with DMP and NaClO2 affords the carboxylic acid (XVIII), which is cyclized to the cyclic amide (XIX). The cleavage of he protecting groups of (XIX) with HCl, followed by selective N-protection with Boc2O, provides primary carbinol (XX), which is finally oxidized with DMP and NaClO2 to give the desired carboxylic acid intermediate (XXI).

Assembly of the target compound: The condensation of the carboxylic acid intermediate (XXI) with the free amino group of the intermediate cyclopeptide (XXII) by means of DEPBT gives the corresponding amide (XXIII), which is cyclized by means of CsF in DMSO yielding the macrocyclic ether (XXIV). The reduction of the nitro group of (XXIV) with H2 over Pd/C affords the corresponding amino derivative (XXV).
