PREPARATION OF BOTH ENANTIOMERS OF A CHIRAL LACTONE THROUGH COMBINED MICROBIOLOGICAL REDUCTION AND OXIDATION
Ouazzani-Chahdi, Jamal,Buisson, Didier,Azerad, Robert

The Baeyer-Williger-like oxidation of (R,S)-2,2,5,5-tetramethyl-4-hydroxy-cyclohexanone by several fungal strains was highly enantioselective, affording a rearranged (S)-hydroxy-γ-lactone.The recovery of the nearly optically pure (R)-hydroxyketone allowed
SYNTHESE DE L'ACIDE CIS CHRYSANTHEMIQUE
d'Angelo, Jean,Revial, Gilbert
, p. 2103 - 2106 (2007/10/02)
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).
