Abstract

Résumé A simple, efficient approach of racemic cis chrysanthemic acid 2 , an intermediate in the synthesis of the exceptionally potent insecticide Deltamethrine 1 , is described. The key-intermediate of this approach was the 2,2,5,5-tetramethylcyclohexane 1,4-dione 5 which has been related to the lactone 3 , a precursor of 2 , in four steps (70 % overall yield).
