The squaramide moiety has proven to be a powerful hydrogen-bonding donor in organocatalysis, but chiral phase-transfer catalysts bearing the squaramide motif have not been reported so far. Reported herein is this kind of catalyst and their catalytic performance in the asymmetric fluorination of β-keto esters.
