Tautomeric equilibrium of naphthazarin thioderivatives

The synthesis of p-tolylsulfenyl, p-tolylsulfinyl and p-tolylsulfonyl naphthazarins (5,8-dihydroxy-1,4-naphthoquinone) with the sulfur function on C-2 or C-6 and all their possible dimethylethers is reported. The detailed study of their 13C-nmr

Synthesis of Optically Active p-Tolylsulfinylquinones

The title compounds 3a-e were prepared in only two steps from 1,4-dimethoxyaromatic precursors 1a-e by sulfinylation followed by oxidation with ammonium cerium(IV) nitrate.

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
