A simple organocatalytic one-pot protocol for the construction of opticallyactive allylic alcohols and amines using readily available reactants and catalyst is presented. The described reaction is enabled by an enantioselective enone epoxidation/aziridination-Wharton-reaction sequence affording two highly privileged and synthetically important classes of compounds in an easy and benign way. The advantages

abstraction occurred (three examples, 65–86% yield). The results are consistent with a reaction course via a tripletenone intermediate and the formation of a 1,4-diradical by an initial cyclization. The analogous cyclopent-2-enones were less prone to an intramolecularreaction. Instead, decomposition or intermolecular [2 + 2] photocycloadditionreactions prevailed. In the latter event, two main products
