"Chemical Equation Presented" A bifunetional quinidine derivative, containing a trifluoromethyl group, was found to catalyze a tandem intramolecular oxa-Michael addition/electrophilic fluorination reaction of acti-vated α,β-unsaturated ketones (see scheme). A series of chiral fluorinated flavanone derivatives were obtained in excellent yields and with high enantioselectivities.
