Abstract
Improvements introduced in the object of the main patent nº. 344,436, filed august 25, 1967, by "a process for the preparation of carboxylic acids and their esters, cyclopropane derivatives, particularly in a process for the preparation of a novel ester of a carboxylic acid derived from cyclopropane, namely 3,3-dimethyl-2-cyclopentylidene-methyl-1-cyclopropanecarboxylic acid and 5-beneyl-3-furylmethyl alcohol of formula (α). ** (see formula) ** Characterized in that the 3,3-dimethyl-2-cyclopentylidene-methyl-1-cyclopropanecarboxylic acid of formula (β) is reacted: ** (see formula) ** Or a functional derivative of this acid, such as the chloride, anhydride, mixed anhydride, ester or metal salt, with the 5-benzyl-3-furyl-methyl alcohol or with a halogenated derivative thereof.
