Abstract
Using chiral palladium enolates as key intermediates, efficient catalytic enantioselective fluorination reactions of active methine compounds have been developed. These reactions can be conducted in alcoholic solvents without any precaution to exclude water and moisture, and various β-ketoesters and β-ketophosphonates were fluorinated in a highly enantioselective manner (up to 98% ee).
