wide range of gem‐bisphosphonate tetraethyl esters as precursors for bisphosphonic acids, which are potent inhibitors of bone resorption, bearing alkyl, aryl, and indole substituents in the β position were prepared through the CuII‐catalyzed 1,4‐conjugate addition of boronic acids and indoles to vinylidenebisphosphonate tetraethyl ester.
