Copper-Catalyzed Diphenylation of P(O)-OH Bonds with Cyclic Diaryliodonium Salts
A copper-catalyzed diphenylation of P(O)?OH bonds with cyclic diaryliodonium salts is described. Valuable 2′-iodo substituted biaryl phosphinic/phosphoric acid esters were obtained in good to excellent yields, which could be further transformed to diversified building blocks for the synthesis of bioactive compounds, pharmaceuticals and functional materials.
This invention relates to ortho substituted phenyl compounds as inhibitors of prostaglandin synthase, to pharmaceutical compositions comprising such compounds and to methods of using such compounds as antiinflammatory and antipyretic agents. The class of compounds useful in this method of treatment is represented by Formula I below: STR1
