The key factors for carbonyl-stabilised ammonium ylide-mediated epoxidation reactions were systematically investigated by experimental and computational means and the hereby obtained energy profiles provide explanations for the observed experimental results. In addition, we were able to identify the first tertiary amine-based chiral auxiliary that allows for high enantioselectivities and high yields for such epoxidation reactions.

A pair of chiral compounds S-1 and R-1 derived from (1S, 2S) or (1R, 2R)-1, 2-diphenylethane-1, 2-diamine were designed and synthesized, the interactions of S-1 and R-1 with mandelate were studied in H2O (0.01 M HEPES buffer, pH = 7.4) by fluorescence titration experiments. The sensors S-1 and R-1 were found to present enantioselective fluorescent sensing ability to mandelate. The results indicated that the sensors S-1 and R-1 were very promising to be used as fluorescent sensors in determining the enantiomeric composition of mandelate in H2O.
