该中间体在本合成路线中的序号：(XVI)For the preparation of tripeptide intermediate (XVIII), N-Cbz-threonine (XII) was coupled with proline benzyl ester (XIII) to give dipeptide (XIV). Subsequent hydrogenolysis of the benzyl groups of (XIV) in the presence of Pd/C furnished threonyl proline (XV). Coupling of (XV) with the succinimidyl ester (XVII) prepared from the protected ornithine (XVI) then provided tripeptide intermediate (XVIII).
