| This reagent provides blocked derivatives having even greater stability than can be achieved employing PC9003. This blocking agent is utilized where the highest stability is desired. Hydroxyl derivatives prepared utilizing PC9004 are stable to 80% acetic acid (which cleaves t-butyldimethylsilyl derivatives), 50% aqueous trifluoroacetic aciddioxane, hydrogenation over Pd, Grignard reagents and lithium alumi-num hydride. Blocked derivatives are very resistant to hydrolysis and oxidation. Derivatization is effi-ciently carried out using a molar excess of imidazole in DMF solvent. Hydrolysis is effected with tetrabutylammonium fluoride in THF. |
