Abstract
Procedure for the obtaining of derivatives of phosphinic and phosphonic acids and of their salts, of formula (I), in which r is rent and r is hydrogen or lower rent, or together with the carbon atomo to which they are united form a cyclocal ring c <003>; r and r are lower rent; and x is hydrogen, hydroxyl, rent or aril. It consists in the reaction of a compound of formula (II) with a cetone of formula r cor, in which all symbols have the same meaning as in formula (I). The reaction is carried out in an aqueous-organic medium, at the reflux temperature of the reaction mixture. Diastereomeric mixing can be separated diastereomeric racematos or resolve the optical isomers. These compounds have pharmacological applications for the treatment of inflammatory states, degenerative articular diseases and wilson's disease.
