合成路线1
该中间体在本合成路线中的序号：(XXVIII)Another route for the synthesis of intermediate (XVIII) has also been described: To resin (XXVI) was coupled N-Fmoc-L-leucine (IV) to afford resin (XXVII), after Fmoc deprotection with piperidine. Subsequent coupling with the protected diaminopropionic acid (III), followed by a new deprotection with piperidine, gave the resin-bound linear peptide (XXVIII). After trifluoroacetic acid-promoted cleavage from the resin, the resultant side-chain-protected peptide was cyclized to (XVIII)
