chiral fluorine‐containing molecules is important for several scientific disciplines. We herein disclose a straightforward method for the preparation of chiral organofluorine molecules that is based on the iridium‐catalyzed asymmetric hydrogenation of trisubstituted alkenyl fluorides. This catalytic asymmetric process enables the synthesis of chiral fluorine molecules with or without carbonyl substitution

Reaction of dimethyl-sulfoxonium methylide with non-halogenated α-ethylenic-ketones is known to lead to cyclopropyl derivatives. With α-fluoro α-ethylenic-ketones this reaction furnishes fluoro-epoxides, by addition of a methylene on carbonyl.

Biocatalytic reduction of 2-fluoro-2-alken-1-ols mediated by Saccharomyces cerevisiae underwent smoothly and yielded (S)-2-fluorinated alkanols with high enantioselectivities. The conversion rate was markedly depending on the configuration of alkene moiety of the substrate, the chain length of alkyl group at beta position of C=C bond, as well as the reaction conditions.
