The palladium-catalyzed Heck reaction of trifluoromethanesulfonates of anthraquinoid systems is described. The outcome of the reaction between methyl acrylate 4 and 1-(9,10-anthraquinoyl)trifluoromethanesulfonate 7 (reduction versus arylation) is strongly correlated to the choice of ligand, solvent, and added salt. The results are explained in terms of different coordination-insertion pathways as a function of the reaction conditions. Best conditions have been transferred to the synthesis of novel anthracyclinone, 4-demethoxy-4-(2'-methoxycarbonyl)ethenyl-13-dioxolanyldaunomycinone 5.
