%X Reaction of 2-formylquinizarin dimethyl ether (3) with the dimethoxy  ylide (6) gives an &#945;,&#946; -unsaturated ester (8) which on hydrogenation, reduction and methylation gives the tetramethoxyanthracene diester (18). When linked to work by Dotz and Popall this sequence provides a route to (±)-4-demethoxydaunomycinone.
