合成路线1
该中间体在本合成路线中的序号:(IX)The title compound has been prepared by either solid-phase or solution-phase synthesis. In the first case, N(alpha)-Boc-N(omega)-nitro-L-arginine (I) was coupled with N,O-dimethylhydroxylamine, and the resulting N-methoxy-amide (II) was reduced with LiAlH4 to the corresponding aldehyde, isolated as the cyclic hemiaminal (III). Deprotection of the N-nitro group of (III) by hydrogenation over Pd/C afforded guanidine (IV), which was condensed with allyl chloroformate to give the allyl carbamate (V). Subsequent acid-catalyzed condensation with ethyl 6-hydroxyhexanoate (VI) at the aminal hydroxyl group provided ketal (VII). After hydrolysis of the ethyl ester of (VII), the resulting carboxylic acid (VIII) was coupled to amino-resin to produce the amide-resin (IX).

合成路线2
该中间体在本合成路线中的序号:(IX)Further solid-phase peptide synthesis by means of sequential coupling of resin (IX) with L-alanine, D-serine and isobutyl chloroformate yielded the peptide-resin (X). The allyloxycarbonyl group of (X) was then removed by treatment with morpholine and palladium catalyst to give resin (XI). The target peptide was finally liberated from the resin (XI) by treatment with trifluoroacetic acid.
