Synthesis of Isomeric 6-Trifluoromethyl-3-azabicyclo[3.1.0]hexanes: Conformationally Restricted Analogues of 4-Trifluoromethylpiperidine

Two isomeric conformationally restricted analogues of 4-trifluoromethylpiperidine were designed. The synthesis was performed in four steps from commercially available N-benzylmaleimide. The key reaction was the [3+2] cycloaddition between trifluoromethyldiazomethane and N-benzylmaleimide.
