derivatives (CED) of alkyl glycopyranuronates with the d -Glc, d -Gal, and d -Man configurations is described by oxidation of the 3,4-di-O-acetyl-6-O-trityl-CED-hexose analogues with the Jones reagent [chromium(VI) oxide-sulfuric acid]. The isopropylidenation of hydroxyl-containing triphenylmethyl ethers is demonstrated.
