GENERAL SYNTHESIS OF CHIRAL 2-P-TOLYLSULFINYLQUINONES

Optically pure (S)-p-tolylsulfinyl substituted quinones were synthesized by deketalization of the corresponding quinone bisketals obtained by Andersen's type synthesis starting from 2-bromo-1,4-dimethoxy aromatic derivatives, followed by anodic oxidation
