Abstract

Procedure for obtaining 2-phosphono-butane-1,2-dicarboxylic acid derivatives, of formula ** (See formula) ** where R is hydrogen, alkyl with up to 4 carbon atoms and the carbonyl group, R1 is hydrogen and methyl and R2 is cyano, the carbonamido group and the carboxyl group; characterized by comprising adding tetraalkyl phosphonosuccinate of the formula: ** (See formula) ** wherein R3 and R4 signify alkyl with up to 4 carbon atoms, compounds bearing activated carbon-carbon double bonds, of the formula: ** (See formula) ** Where R1 has the meaning indicated above, R5 means hydrogen, alkyl and carboxyalkyl, in each case with up to 4 carbon atoms and R6 means cyano, the carbonamido group and the carboxyalkyl group, in the presence of catalytically active strong bases; and saponify the formula addition products ** (See formula) ** in which R1, R3, R4, R5 and R6 have the indicated meaning, with aqueous mineral acids.
