, p. 2103 - 2106 (1983)
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 percent overall yield).
