Bicyclo[3.2.1]octane (BCO) skeleton widely exists in natural products and biologically active molecules, whereas the development of convenient approaches to construct this structure remains a challenge. Herein, we describe a cascade reaction to synthesize 6,8-dioxa-3-azabicycle[3.2.1]octane derivatives from β-keto allylamines via an oxidation-cyclization reaction. A series of dioxo-azabicyclo[3.2.1]octanes bearing a quaternary carbon center were obtained in good yields under mild reaction conditions. Moreover, the mechanistic rationale for this novel domino reaction is supported by control experiments.
