合成路线1
该中间体在本合成路线中的序号：(XVII)The peptide resin (XV) was then coupled with tert-butyl hydrogensuccinate (XVI) yielding resin (XVII). Further Dess-Martin oxidation of the alpha-hydroxyamide function of (XVII) gave rise to keto amide (XVIII). Finally, simultaneous cleavage from the resin and deprotection of the tert-butyl ester groups of (XVIII) by treatment with trifluoroacetic acid provided the title peptide amide.
