Abstract: | Although asymmetric phosphine catalysis is a powerful tool for the construction of various chiral carbon centers, its synthetic potential toward an enantioenriched atropisomer has not been explored yet. Reported herein is a phosphine‐catalyzed atroposelective (4+2) annulation of δ‐acetoxy allenoates and 2‐hydroxyquinone derivatives. The reaction provides expedient access to aryl‐naphthaquinone atropisomers by the de novo construction of a benzene ring. The two functionalities of the catalyst, a tertiary phosphine (Lewis base) and a tertiary amine (Brønsted base), cooperatively enable this process with high regio‐ and enantioselectivities. |
