SYNTHESIS OF 1,2-O-CYANOETHYLIDENE DERIVATIVES OF ALKYL GLYCOPYRANURONATES BY OXIDATION OF THE 6-TRITYL ETHERS OF THEIR HEXOSE ANALOGUES

Article abstract of DOI:10.1016/0008-6215(88)84108-9

The synthesis of 1,2-O-cyanoethylidene 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 .The isopropylidenation of hydroxyl-containing triphenylmethyl ethers is demonstrated.
