A NEW EFFICIENT SYNTHESIS OF ω-AMINOALKYLIDENE-1,1-BISPHOSPHONATE TETRAETHYLESTERS
摘要:
Bisphosphonates are interesting therapeutic agents in the management of bone diseases and since several years our laboratory has been developing the chemistry of 1,1-bisphosphonates, This paper describes an original synthesis of two aminoalkylidenebisphosphonates by first preparing the intermediate hydroxyalkylidenebisphosphonates which are transformed into amines via the azides.
