In an alternative method, 2,3-bis(benzyloxy)benzoic acid (VII) was activated as the corresponding imidazolide (VIII) prior to condensation with norspermidine (IX). The resulting diamide (X) was further acylated with N-(benzyloxycarbonyl)-D-threonine (II) to afford triamide (XI). Hydrogenolysis of the O-benzyl and N-benzyloxycarbonyl protecting groups of (XI) then gave amino alcohol (V), which was finally cyclized with imidate (VI) as above.
