Summary: | Graphic
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. |
