The enantioselective synthesis of axiallychiralbiaryls by a copper-catalyzed Diels–Alder/retro-Diels–Alder reaction of 2-pyrones with alkynes is reported herein. Using electron-deficient 2-pyrones and electron-rich 1-naphthyl acetylenes as the reaction partners, a broad range of axiallychiralbiaryl esters are obtained in excellent yields (up to 97% yield) and enantioselectivities (up to >99% ee)
