Document Type and Number:
Japanese Patent JPS54144341
Kind Code:
A
Abstract:
Novel 2-formyl-3,3-dimethylcyclopropylacetic acid, its esters, salts or dialkylacetals are prepared by a process which comprises ozonolysis of 3-acetyl-6,6-dimethylbicyclo ¢3.1.0!-2-hexene, reductive cleavage of the ozonide product thus found, and optionally converting the free acid into an ester, a salt or a dialkyl acetal. The acetic acid derivative is an intermediate in the manufacture of pyrethroid insecticides. The bicyclohexene starting material is preferably obtained from the naturally-occurring terpene (+)-3-carene.
