摘要：

Chiral 3,4-dihydrocoumarin derivatives were obtained from 2-benzyl phenols and oxazolones in moderate to high yields with excellent enantioselectivitie (up to 96 % ee) through one-pot cascade via C-H oxidation and cyclization cascade using a binaphthyl-modified squaramide bifunctional organocatalyst under mild reaction conditions.
