This strategy is based on the use of the 2-naphthylmethyl (Nap) ethers and levulinoyl (Lev) ester for permanent protection of hydroxyls. Removal of seven Nap ethers by 2,3-dichloro-5,6-dicyano-1,4-benzoquinone made it possible to prepare GPIs having an alkyne functionality that could be modified by Cu(I)-catalyzed [3 + 2] cycloadditions to install tags for imaging studies.
