In the present paper, the Cu(I)-catalyzed intramolecular aminotrifluoromethylation of O-homoallyl benzimidates with Togni reagent I was reported. O-Homoallyl benzimidates equipped with terminal alkenes produced chiral 1,3-oxazines with high enantioselectivity in the presence of a chiral BOX ligand, and racemic tetrahydro-1,3-oxazepines were obtained in high yields from internal alkene derivatives with
