(Chemical Equation Presented) A new mode of chiral anion catalysis: A powerful chiral-counteranion strategy for catalytic asymmetric epoxidations using the newly discovered catalyst 1 has been applied to the epoxidation of α,β-unsaturated aldehydes together with tert-butyl hydroperoxide as the oxidant (see scheme). Remarkably, this system provides the corresponding epoxides in high diastereo- and enantioselectivity for both di- and trisubstituted enals.

The products and the kinetics of the epoxidation of trans-3-arylpropenals with tert-butyl hydrogen peroxide in an alkaline medium were studied.The epoxidation rate increases with increase in the electron-withdrawing characteristics of the substituents in the aryl fragment of cinnamaldehydes.
