合成路线1
该中间体在本合成路线中的序号：(VI)The compound was prepared by solid-phase peptide synthesis on a poliethylene glycol amino resin. Coupling with N(alpha)-Fmoc-N(G)-Boc-lysine (I) using O-benzotriazol-1-yl-N,N,N',N'-tetramethyluronium hexafluorophosphate (HBTU) and N-methylmorpholine (NMM) afforded the protected lysine-linked resin (II), and subsequent Fmoc deprotection provided resin (III). This was submitted to further coupling and deprotection cycles with the N(alpha)-Fmoc-protected amino acids proline (IV), N(G)-(2,2,4,6,7-pentamethyldihydrobenzofuran-5-sulfonyl)arginine (VI), D-alanine (VIII), N(G)-Pbf-arginine (VI), and again N(G)-Pbf-arginine (VI) yielding peptide resins (V), (VII), (IX), (X) and (XI).
