A new protocol of the synthesis of 3,3′-diaryl-3,3′-diphthalides by dehalogenation of o-keto carboxylic acid pseudochlorides is implemented. The feature of the new protocol is that the reaction is carried out in the presence of a zero-valent nickel comple

A new general methodology for the anthraquinone and anthracyclinone synthesis has been developed.In contrast to the data reported in the previous literature, anthraquinones can be obtained under mild conditions from ortho dicarboxylic acid chlorides and suitable aromatic substrates via a Friedel-Crafts process.In this context the classic Wong synthesis of anthracyclinones has been greatly improved.The study of the reaction mechanism permitted the unexpected results to be rationalized and to account for the "ortho template bisacylation" of the phenol substrates.
