Abstract
The weak basic bicarbonate-activated hydrogen peroxide is applied to the catalytic asymmetric epoxidation of the enones, and the catalyst polyleucine cannot be deteriorated and can successfully be reused in this asymmetric reaction. The ee value of the optically active epoxidation product is up to 95%.
