title: Transition-Metal-Free Coupling Annulation of Arynes with Ketones and Alkynoates: Assembly of Functionalized Naphthalenes.
abstract: A transition-metal-free coupling annulation reaction of arynes, ketones, and alkynoates has been demonstrated. Using this formal [2 + 2 + 2] cycloaddition reaction, a wide variety of naphthalene derivatives were conveniently constructed in one pot with high efficiency. In addition, this novel and valid annulation has been successfully applied to the synthesis of 1-phenanthrenol derivatives.
