A new entry to the synthesis of 1,2-benzenediol congeners
1,2-Benzenediols were synthesized via 1,1-bis(ethylthio)-3-cyclohexen-2-one derivatives, which were prepared by condensation of 1,1-bis(ethylthio)-2-propanone with Mannich bases. Regioselective preparation of their monoethers was also achieved.

A NEW ENTRY TO 1,2-BENZENEDIOL CONGENERS
1,2-Benzenediols and their monoethers were efficiently prepared from α,α-bis(ethylthio)cyclohexenones which were constructed by the C3+C3 annulation of 1,1-bis(ethylthio)propan-2-one and the Mannich bases. KEYWORDS 1,2-benzenediol; aromatic synthesis; annulation; aromatic compound; acetal
