Abstract
A process for enantioselectively epoxidising a prochiral olefin, which process comprises reacting a prochiral olefin with a source of oxygen in the presence of a salen catalyst and a source of an electron donating ligand, characterized in that the donor ligand is isoquinoline N-oxide or a compound having donor ligand activity and having substantially the same solubility characteristics as isoquinoline N-oxide.
