The new convenient synthesis of functionalized aryl and pyridyl aminomethylenebisphosphonic acids and their derivatives has been developed via silicon-assisted methodology. New functionalized aminomethylenebisphosphonic acids containing pyridines moieties were obtained using unique reaction of tris(trimethylsilyl) phosphite with N-formyl aminopyridines and trimethylsilyl triflate as a catalyst under
A facile synthesis of aminomethylene bisphosphonates through rhodium carbenoid mediated N–H insertion reaction. Application to the preparation of powerful uranyl ligands
onto aromatic amines is described. The procedure yields aminoaryl 1,1-bisphosphonates known to display multiple biological activities. The described methodology has also been applied to the synthesis of ligands whose uranyl-binding properties have been studied.

the first committed step of cholesterol biosynthesis is catalyzed by squalenesynthase, we explored whether inhibiting this enzyme protected cells against cholesterol‐dependent cytolysins. We first synthesized 22 different nitrogen‐containing bisphosphonate molecules that were designed to inhibitsqualenesynthase. Squalenesynthase inhibition was quantified using a cell‐free enzyme assay, and validated
