合成路线1
该中间体在本合成路线中的序号：(XXII)Coupling between segments (VI) and (XXI) by means of HBTU gave rise to the depsipeptide (XXII). Simultaneous deprotection of the C- and N-terminal functions of (XXII) by hydrogenolysis led to the linear precursor (XXIII), which was then cyclized to (XXIV) in the presence of HATU and HOAt
