Synthesis of a new heterocyclic system, 2, 5-diazabicyclo [4. 1. 0] heptane, substituted on nitrogen, has been achieved by the reaction of the disodium or dipotassium salt of cis-1, 2- (arenesulfonamido) cyclopropane with ethylene bromide. Analysis of the 1H magnetic resonance spectrum demonstrated that this bicyclic system exists as a mixture of interconverting enantiomeric half-chair conformers.
