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.

A method of purifying tetraethylorthosilicate (TEOS) to remove boron impurities therefrom, and a related method of analyzing TEOS to determine concentration of boron impurities therein.
capabilities of inositols as carbohydrate substitutes. The conformational features of an inositol-model of a simplified repeatingunit corresponding to the capsular polysaccharide of Streptococcuspneumoniae 19F has been evaluated by computational analysis, and compared to the native repeatingunit. The inositol mimic was synthesized, and its experimental spectroscopic data allowed for verification of the theoretical
