该中间体在本合成路线中的序号：(VIII)The title compound was synthesized by stepwise solid-phase peptide synthesis, starting from the protected arginine linked to PAM resin (I). After deprotection of the Boc group of (I) with trifluoroacetic acid, coupling with (Boc)-tryptophan (II) in the presence of TBTU and diisopropylethylamine afforded the dipeptide resin (III). Sequential deprotection and coupling cycles with (Boc)-D-cyclohexylalanine (IV), (Boc)-proline (VI), (Boc)-ornithine (VIII), and (Fmoc)-phenylalanine (X) provided the resins (V), (VII), (IX) and (XI), respectively.
