合成路线1
该中间体在本合成路线中的序号：(VIII)The anchoring of Fmoc-D-Val-OH (I) to Cl-TrtCl-RESIN (II) by means of DIEA, followed by cleavage of the Fmoc protecting group with piperidine in DMF, gives the resin-bonded valine (III), which is submitted to successive deprotection/coupling cycles with Fmoc-D-allo-Ile-OH (IV), Fmoc-D-allo-Thr-OH (VI) and again Fmoc-D-allo-Ile-OH (IV) to yield peptide resins (V), (VII) and (VIII), respectively. The coupling of Alloc-L-Val-OH (IX) to the free OH group of the Thr amino acid of peptide resin (VII) by means of DIPCDI and DMAP affords peptide resin (X), which is submitted to successive deprotection/coupling cycles with Fmoc-L-Orn(Boc)-OH (XI), Fmoc-D-Pro-OH (XIII) and Fmoc-D-Val-OH (I) to provide peptide resins (XII), (XIV) and (XV), respectively.
