摘要

Epoxidation of a series of poly-oxygenated chalcones with H2O2 in the presence of poly-α- aminoacid catalysts afforded chiral aromatic oxygenated epoxides in moderate to high optical yields; their absolute configurations were determined by CD spectroscopy. These chalcone epoxides could, in principle, be used as chirons for enantiomerically enriched dihydroflavonols.
