GRAPHICAL ABSTRACT Abstract Syntheticapproaches for conjugating 3,5-bis(arylidene)-4-piperidones with bisphosphonate moiety were elaborated. These approaches are based either on reaction of Grignard reagent containing dioxolane protected 4-piperidone with tetraethyl ethylidenbisphosphonate followed by crotonic condensation with aromatic aldehydes or on Cu(i) catalyzed 1,3-cycloaddition of tetraethyl

An approach to the synthesis of new conjugates of 3,5-bis(arylidene)-4-piperidone pharmacophore with bisphosphonate moiety separated from the nitrogen atom of piperidone ring by four methylene units has been developed. This approach is based on the reaction of tetraethyl vinylidene-1,1-bisphosphonate with the Grignard reagent containing a dioxolane-protected piperidone ring (4-piperidone ethylene ketal)
