Chiral amino acid-based hydroxamic acids can be effective asymmetric catalysts for the epoxidation of allylic alcohols, especially disubstituted allylic alcohols. The mild reaction conditions, e.g., reasonable temperature, low degree of catalyst loading, and halogen-free solvent, extend the scope of this process.
