Urea–hydrogen peroxide prompted the selective and controlled oxidation of thioglycosides into sulfoxides and sulfones

A practical method for the selective and controlled oxidation of thioglycosides to corresponding glycosyl sulfoxides and sulfones is reported using urea–hydrogen peroxide (UHP). A wide range of glycosyl sulfoxides are selectively achieved using 1.5 equiv of UHP at 60 °C while corresponding sulfones are achieved using 2.5 equiv of UHP at 80 °C in acetic acid. Remarkably, oxidation susceptible olefin functional groups were found to be stable during the oxidation of sulfide.

VINYL SULPHONES DERIVED FROM THIOGLYCOSIDES: SYNTHESIS AND ALKYLATION

Vinyl sulphones (1-sulfonyl glycals) are formed in good yield by elimination of propanone from 2,3-O-isopropylidene derivatives of D-mannopyranosyl and L-rhamnopyranosyl sulphones.Attempted conjugate addition of carbon nucleophiles to these vinyl sulphones, which are deactivated towards nucleophiles by the ring oxygen atom, was unsuccessful but lithiation followed by methylation yielded the 2-methyl vinyl sulphone derivatives when t-butyl sulphones rather than phenyl sulphones were used.
