资源简介：
BF3·etherate-mediated carbon–carbon bond formation by the Friedel–Crafts arylation 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 derivatives under mild conditions.
