合成路线1
该中间体在本合成路线中的序号：(VI)Fmoc-protected phenylalanine (I) is attached to Rink resin by means of DCC and HOBt coupling, to give the amino acid-resin complex (II). Then, N-Fmoc protecting group is removed with piperidine in DMF to afford (III). This is submitted to further sequential amino acid coupling and deprotection cycles with Fmoc-phenylalanine (I) and alpha-Fmoc-omega-pmc-D-arginine (VI) to yield in turn resins (V) and (VII), respectively.

合成路线2
该中间体在本合成路线中的序号：(III)The title compound was prepared by solid-phase peptide synthesis starting from N-Fmoc-D-proline linked to Rink resin (I). Deprotection of the Fmoc group by means of piperidine in DMA afforded proline-resin (II). Coupling of N-alpha-Fmoc-NG-Pmc-D-arginine (III) to proline-resin (II) using diisopropyl carbodiimide (DIC) and HOBt, followed by Fmoc deprotection with piperidine in DMA, furnished dipeptide-resin (IV). Further coupling and deprotection cycles incorporating the amino acid N2-Fmoc-N6-Boc-D-lysine (V) (twice) and the peptoid residue N-Fmoc-N-[3-(3-Pmc-guanidino)propyl]glycine (VIII) yielded the peptide resins (VI), (VII) and (IX), respectively.
