Layered catalyst: The attachment of α‐amino acid ligands to inorganic nanosheets for use as ligands to vanadium, resulted in a catalyst that enhanced the enantioselectivity of the epoxidation of allylic alcohols (see picture) . The catalyst can be colloidized, allowing for the catalytic reactions to be carried out under pseudo‐homogeneous reaction conditions and also the catalysts to be directly recycled
