The α,α-bis(trimethylsilyl)-o-toluamides 4 and 9, systems protected from benzylic deprotonation, are available starting materials for the short syntheses of peri-methyl substituted benz[a]anthraquinones 6a and 6b and desoxyerythrolaccin trimethyl ether 12 respectively.

We report that ruthenium complexes effectively catalyzed the carboxylate-directed addition of aromatic C–H bonds to aldehydes. The reactions of aromatic acids with a variety of aromatic aldehydes including unactivated ones proceeded efficiently to give the corresponding isobenzofuranone derivatives in high yields. The combination of ruthenium(II) complexes with tricyclohexylphosphine led to highly
