合成路线1
该中间体在本合成路线中的序号:(VIII)Compound (XI) was prepared by solid phase peptide synthesis on a Rink amide 4-methylbenzhydrylamine (MBHA) resin. After removal of Fmoc protecting group from the resin with 20% piperidine in N-methyl-2-pyrrolidinone (NMP), a coupling cycle was carried out with Fmoc-Thr(O-t-Bu)OH (I) using bromotripyrrolidino phosphonium hexafluorophosphate (PyBroP) and diisopropylethylamine (DIEA) in NMP, followed by Fmoc removal with 20% piperidine in NMP. To the Thr-bound resin (II) they were stepwise coupled in subsequent coupling and deprotecting cycles the following amino acids: Fmoc- (N-allyloxycarbonylpropyl)PheOH (IV), Fmoc-ValCl (VI), Fmoc-Lys(Boc)OH (VIII), and Fmoc-D-TrpOH (X) to yield the corresponding peptide-bound resins (V), (VII), (IX) and (XI), respectively.

该中间体在本合成路线中的序号:(V)The title compound was obtained by solid-phase peptide synthesis starting from N-Boc-S-(4-methylbenzyl)cysteine linked to PAM resin (I). The protected peptide template (XVII) was synthesized by sequential coupling-deprotection cycles using the appropriate combination of either Boc- or Fmoc- N-alpha-protected amino acids. The following side-chain-protected amino acid residues were assembled: Gly (III), Lys(Boc) (V), Glu(cyclohexyl ester) (VII), Lys(Boc) (V), Pro (X), Gly (III), Lys(Boc) (V), Lys(chlorobenzyloxycarbonyl) (XIV) and Lys(Boc) (XVI) to produce the peptide resins (IV), (VI), (VIII), (IX), (XI), (XII), (XIII), (XV) and (XVII), respectively. Subsequent removal of the N-terminal and the four side-chain Boc protecting groups by means of trifluoroacetic acid yielded the peptide resin (XVIII).

该中间体在本合成路线中的序号:(I)Coupling of N-alpha-Fmoc-N-epsilon-Boc-lysine (I) to 7-amino-4-methylcoumarin (II) by means of DCC produces the lysine amide (III). After acidic cleavage of the N-Boc protecting group of (III), the resultant primary amine (IV) is attached to chlorotrityl resin to produce (V). The Fmoc group of (V) is then removed with piperidine in DMF, yielding the lysinamide-bound resin (VI). Further coupling with N-Fmoc-cyclohexylalanine (VII) employing TBTU/HOAt furnishes the dipeptide amide resin (VIII). The title compound is finally cleaved from the solid support by means of trifluoroacetic acid in CH2Cl2.
