Transition Metal‐Free Vinylcyclopropanation of Olefins via Carbolithiation Reactions: Synthesis of 3‐Azabicyclo[3.1.0]hexanes

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 17, 1 September 2026.
Readily accessible N‐allyl‐N‐2‐bromoallylamines undergo a tandem lithiation–cyclization cascade to furnish highly substituted 3‐azabicyclo[3.1.0]hexanes. The transformation proceeds without transition metals and delivers products with excellent diastereocontrol across a broad substrate range.
