Catalytic Enantioselective Synthesis of Chiral Organofluorine Compounds: Alcohol-Mediated Hydrogen Transfer for Catalytic Carbonyl Reductive Coupling.

Alcohol-mediated carbonyl addition has enabled catalytic enantioselective syntheses of diverse fluorine-containing compounds without the need for stoichiometric metals or discrete redox manipulations. Reactions of this type may be separated into two broad categories: redox-neutral hydrogen auto-transfer reactions wherein lower alcohols and n-unsaturated pronucleophiles are converted to higher alcohols and corresponding 2-propanol mediated carbonyl reductive couplings.
