合成路线1
The compound was prepared by solid-phase synthesis. Condensation of tert-butyl carbazate (I) with 1,1'-carbonyldiimidazole (II) afforded the acyl imidazole (III). Coupling of (III) with amino resin produced the Boc-protected semicarbazide-linked resin (IV), which was deprotected with trifluoroacetic acid to give (V). Condensation of (V) with protected L-argininal (VI) provided the semicarbazone resin (VII). Further solid-phase peptide synthesis by means of sequential coupling with L-alanine, D-serine and phenethylsulfonyl chloride yielded the peptide-resin (VIII). Finally, deprotection of both Boc groups of (VIII) with concomitant resin cleavage by means of aqueous trifluoroacetic acid furnished the target compound.
