The rational synthesis of fenidronate

The synthesis of the disodium salt of fenidronate by the reaction of benzoic acid with phosphorus trichloride and phosphorous acid in methanesulfonic acid was investigated and optimized. It was enough to use 3.2 equivalents of phosphorus trichloride and t

Synthesis of α-hydroxy-methylenebisphos-phonates by the microwave-assisted reaction of α-oxophosphonates and dialkyl phosphites under solvent ess conditions

The synthesis of hydroxy-methyl-enebisphosphonates (2a-c) by the addition of dialkyl phosphite to the carbonyl group of the corresponding α-oxophosphonate (1a-c) was studied under microwave irradiation (MW) and solventless conditions in the presence of di

α CETOPHOSPHONATES ET ESTERS CYCLIQUES D'HYDROXYMETHYLENES DIPHOSPHONATES SYNTHESES, STRUCTURES ET HYDROLYSE

Synthesis of symmetrical diesters derived from hydroxy methylene diphosphonic acids 1 to 8 is described either in one step or via the corresponding α ketophosphonate 1a to 8a.Study of the diphosphonates (1 to 6) -> phosphate-phosphonates (1b to 6b) isomerization has been realized.Results related to peculiar cases in connection with nonsymmetrical esters 10, 11, 17 and study of the hydrolysis reaction of diphosphonates are presented.
