Catalytic asymmetric synthesis of epoxides mediated by chiral iminium salts
TL;DR: The catalytic asymmetric oxidation of unfunctionalised alkenes is achieved by a non-transition metal catalysed process; just 5 mol% of the binaphthyl-based iminium salt 1 is sufficient to catalyse the oxidation of alkenses to epoxides with moderate to good enantioselectivity.
