The first direct enantioselective catalytic alpha-fluorination of aldehydes has been accomplished. The use of enamine catalysis has provided a new organocatalytic strategy for the enantioselective fluorination of aldehydes to generate alpha-fluoro aldehydes, an important chiral synthon for medicinal agent synthesis.
