合成路线1
该中间体在本合成路线中的序号：(VIII)Compound (VII) is submitted to amino acid coupling and deprotection cycle with O-t-Bu-alpha-Fmoc-tyrosine (IX), to yield resin (XI). Finally, acidic treatment of (XI) with trifluoroacetic acid in anisole and dichloromethane simultaneously effects deprotection of the O-tert-butyl and N-2,2,5,7,8-pentamethylchroman-6-sulfonyl (Pmc) groups, and liberates the peptide amide from the resin.
