摘要
A novel asymmetric preparation of optically enriched 2-aryl-2,3-dihydroquinolin-4(1H)-ones has been developed. By installing a sulfonyl group on the nitrogen of the anilines and an ester function on the unsaturated ketones, an intramolecular organocatalytic cyclization took place readily in a stereoselective manner, resulting in the formation of dihydroquinolones with high enantioselectivity.
