合成路线1
该中间体在本合成路线中的序号:(IX)Coupling between N-Boc-O-benzyl-L-threonine (VII) and L-leucine benzyl ester (VIII) by means of DCC/HOBt gives the protected dipeptide (IX). Subsequent N-Boc group cleavage in (IX) upon treatment with formic acid yields (X). Further coupling of dipeptide (X) with N-Boc-L-phenylalanine (XI), followed by formic acid deprotection, leads to the benzyl-protected tripeptide (XII).
