This paper presents the synthesis of epibatidineanalogues by a straightforward one-pot method for the synthesis of 7-azabicyclo[2.2.1]heptane-1-carbonitriles, starting from cyclohexanones bearing a leaving group at the 4-position. In situ imine formation, followed by reversible cyanide addition, allows complete conversion of 4-(mesyloxy)cyclohexanone to the bicyclic core. Elaboration of the introduced
