Zinc tert-butyl peroxide-based catalysts for the asymmetric epoxidation of enones using tert-butyl hydroperoxide as an oxidant have been developed. A comparative study of chiral monoanioninc N,N′-bidentate ligands, C2-symmetric bisoxazolinates and C1-symmetric enaminooxazolinates, revealed excellent performance of C1-symmetric auxiliary ligands on catalytic asymmetric epoxidation of enones (up to 96% yield, 91% ee).
