Abstract—A strong enhancement of the enantiomeric excess can be obtained by performing the enantioselective aldol reaction of Chan’s diene in the presence of enantiomerically enriched Ti(O-i-Pr)4/BINOL catalysts derived from mixing pre-prepared solutions of enantiopure Ti(O-i-Pr)4/(R)-BINOL and Ti(O-i-Pr)4/(S)-BINOL at different concentrations.
