Abstract
1,246,813. d-Trans-pyrethic acid. ROUSSEL UCLAF. 11 Nov., 1968 [10 Nov., 1967], No. 53375/68. Heading C2C. d-Trans-pyrethic acid is prepared by reacting 3,3-dimethyl-2-(R). formyl – 1 – (R) – cyclopropane carboxylic acid with a Wittig reagent which in the presence of a strong basic agent yields a carbanion of partial formula The reagent is preferably a substituted phosphonate of in which R represents an alkyl (1-12 C) radical, and other phosphonium salts, phosphine oxides and phosphinic esters are mentioned. The reaction may be performed in an anhydrous organic solvent in the presence of a strong basic agent. Salts of the acid particularly alkali metal salts, the salt of L(+)- or D(-) – threo – 1 – p – nitrophenyl – 2 – N,N – dimethylaminopropane – 1,3 – diol or the salt of 1-quinine may be prepared.
