title: BF3·etherate-mediated Friedel-Crafts arylation of 2-hydroxy-1,4-benzoxazines: synthesis of 2-aryl-1,4-benzoxazine derivatives.
abstract: 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.
