A new straightforward access to benzoxazinones based on a three-component coupling is presented here. The mechanism of the whole process involves a double aryl transfer as clearly underlined by the X-ray diffraction analysis of the products. A new straightforward access to benzoxazinones based on a three-component coupling is presented here.
