Functional bisphosphonate synthesis for the development of new anti-resorption bone drug candidates?

Abstract

Herein we present the synthesis of β-mono and β-bis-substituted vinylidenebisphosphonate esters bearing a carboxylic ester moiety to be used as building blocks for further functionalizations. Reactions of these new bisphosphonate scaffolds through hydrogenation of the unsaturated C[double bond, length as m-dash]C bond and through metal mediated addition of aryl boronic acids and indoles provide a wide range of new bisphosphonate products as potential leads to contrast osteoporosis.
