| titleOfInvention | Process for the preparation of 3-substituted cyclo-propane-1-carboxylic acids and products obtained |
| abstract | A novel process for the preparation of a compound of the formula <IMAGE> I wherein X is selected from the group consisting of oxygen and sulfur and n is 1,2 or 3 comprising reacting in an organic solvent in the presence of a strong base the lactone of cis 2,2-dimethyl-3S-(dihydroxymethyl)-cyclopropane-1R-carboxylic acid with a compound of the formula <IMAGE> III to obtain a compound of the formula <IMAGE> IV reacting the latter with an acid agent in an apolar organic solvent to obtain a compound of the formula <IMAGE> and reacting the latter with a basic agent in an apolar organic solvent to obtain a compound of formula I useful for the preparation of insecticidal esters and the novel compounds of formula I wherein n is 1 or 3. |
