A range of 2-substituted-2,4-endo-dimethyl-8-oxabicyclo[3.2.1]octan-3-ones was studied for its use as a catalyst for the asymmetric epoxidation of some alkenes with oxone. Initial epoxidation reactions were conducted on trans-β-methylstyrene and trans-sti

The first asymmetric epoxidation of isolated carbon–carbon double bonds by a chiral salen complex using ubiquitous Fe(III) as a center-metal is described. By simultaneously introducing fluorous tags and tert-butyl groups into the ligand of the salen compl

New biaryl iminium salt catalysts for enantioselective alkene epoxidation containing additional substitution in the heterocyclic ring are reported. The effects upon conformation and enantioselectivity of this additional substitution, and the influence of dihedral angle in these systems, has been investigated using a synthetic approach supported by density functional theory. Enantioselectivities of up to 97% ee were observed.
