Palladium-Catalyzed Phosphorylation of Aryl Mesylates and Tosylates

The first general palladium catalyst for the phosphorylation of aryl mesylates and tosylates is reported. The newly developed system exhibits excellent functional group compatibility. For instance, free amino, keto, ester, and amido groups, as well as heterocycles, remain intact during the course of reaction. The mesylated derivatives of biologically active compounds such as 17 beta-estradiol and 6-hydroxyflavone are also shown to be applicable substrates. A one-pot phosphorylation-amination sequence is described for the facile synthesis of potential phannacophores.
