该中间体在本合成路线中的序号：(XXIV)In an alternative procedure, initial anchoring of N-Fmoc-L-phenylalanine (IX) to the chlorotrityl resin afforded resin (XXI), which was deprotected with piperidine in DMF to provide the phenylalanine-resin (XXII). Sequential coupling and deprotection cycles with N-Fmoc-L-tryptophan (XI), N-Fmoc-L-aspartic acid beta-t-butyl ester (XIII), and N-Fmoc-N’-(tetraacetyl-beta-D-glycosyl)asparragine (XXV) yielded the peptide resins (XXIII), (XXIV) and (XXVI), respectively.
