该中间体在本合成路线中的序号:(III)

Coupling between N-Boc-aspartic acid (I) and dimethyl aspartate (II) using EDC and DMAP affords tripeptide (III). Subsequent Boc group deprotection in (III) employing trifluoroacetic acid leads to amine (IV).This is then coupled to the polyethyleneglycol-acid (V) producing amide (VI). Basic hydrolysis of the ester groups of (VI) then gives the tetra-carboxylic acid scaffold (VII).
