Abstract 1-2-Dimethoxy-3-methoxymethoxybenzene, 1, was used as the starting material for the transformation of a 1, 2, 3-trioxybenzene into various 1-oxy-2, 3-dicarbobenzenes, via regioselective reductive electrophilic substitution of the 2-methoxy group followed by Pd- catalyzed cross-coupling reaction.
