The difluorides obtained in the reaction of DAST with appropriate ketones could serve as a suitable starting materials for the selective incorporation of CF2-group into the molecules of the unsaturated chiral natural compounds. As an example, stereoselective synthesis of (R)-14,14-difluoro-13-hydroxy-9(Z) ,11(E)-octadecadienoic acid [(R)-14, 14-difluorocoriolic acid] 6 is reported.

The olefination of an enzymatically derived gamma-peroxy-alpha,beta-unsaturated aldehyde (1) allows the synthesis of optically active diene hydroperoxides in high enantiomeric excess. The application of this method to the synthesis of 13(S)-hydroperoxy-9(Z),11(E)-octadecadienoic acid methyl ester is presented.
