BF3·etherate-mediated carbon–carbon bond formation by the Friedel–Craftsarylation of 2-hydroxybenzoxazine derivatives with various electron-rich arenes is reported. The current protocol provides an easy access for the synthesis of a series of densely substituted 2-aryl-1,4-benzoxazine derivativesunder mild conditions.
