Catalytic oxidation-phosphorylation of glycals: rate acceleration and enhancement of selectivity with added nitrogen ligands in common organic solvents

Org Lett. 2005 Feb 17;7(4):725-8. doi: 10.1021/ol047417k.

Abstract

The first general catalytic oxidation of glycals has been developed to afford useful glycosyl phosphates in high yield and selectivity in a domino process with the use of catalytic methyltrioxorhenium, urea hydrogen peroxide, stoichiometric dibutyl phosphate as nucleophile, and a substoichiometric amount of nitrogen ligands, such as pyridine or imidazole, in organic solvents.
