Catalyticasymmetric all-carbon-based inverse-electron-demand Diels–Alderreactions of 2-pyrones with electronically unbiased indenes have been realized. This method enables the rapid and enantioselective construction of a wide range of hexahydrofluorenyl bridged-lactone scaffolds. Based on this method, asymmetric total syntheses of cephanolides A and B have been accomplished.
