چکیده
|
A series of chiral ligands were conveniently prepared from l-phenylalanine and characterized. their application to the asymmetric epoxidation of chalcone was studied. the results demonstrated that 3a were efficient catalysts for enantioselective epoxidation of chalcone in moderate yield (up to 58.6%) and high enantioselectivities (up to 90% e.e.).
