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).

A novel N-iminoylimidazolium salt serves as a precursor to an iminoyl-substituted N-heterocyclic carbene ligand system with the potential to form 5-ring chelates. Reaction of 3-Me-1-[C(C6H5)N(2,6-iPr2C6H3)]C3H3N2+Cl- (3; (C-N)H+Cl-)
