| titleOfInvention | PROCEDURE FOR DEFENDING D, L-CIS AND D, L-TRANS 2,2-DIMETHYL-3- (2,2-DIHALOGENOVINYL) CYCLOPROPA- NO-1-CARBOXYL ACIDS |
| abstract | Cleavage procedure for D, L-cis and D, L-trans 2,2-dimethyl-3- (2,2-dihalogenovinyl) cyclopropane-1-carboxylic acids of formula I: *** (Formula I) * ** in which X represents a fluorine, chlorine or bromine atom, characterized in that an acid of formula (I) is salified with an optically active base, chosen from the group consisting of D-ephedrine, L-ephedrine, DN-methylephedrine, LN-methylephedrine, D-pseudoephedrine, L-pseudoephedrine, the crystalline salt formed corresponding to the acid and base used is isolated and, later, said salt is decomposed by acid hydrolysis, to obtain the cleaved acid corresponding to the acid (I) used. |
