An efficient approach towards the synthesis of monoprotected azabicyclo[5.1.0]octane-derived conformationallyrestricted γ-amino acids and diamines is reported. Optimization of the conditions for the key Corey–Chaykovsky reaction allowed the construction of two isomeric methanoazepane frameworks on a multigram scale in 55–65% yield. Additionally, the developed approach was used in the three-step synthesis
