Alkoxyallenes in Modern Synthesis: Reactivity, Catalysis, and Complexity Generation

Advanced Synthesis &Catalysis, Volume 368, Issue 17, 1 September 2026.
The last decade has witnessed a remarkable transformation in alkoxyallene chemistry. Although historically employed as synthetic equivalents of acrolein or as versatile 3C synthons, alkoxyallenes are now increasingly recognized as highly adaptable platforms for synthetic design.

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

Advanced 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.

Overview of Photochemical Reactions for the Synthesis of Aza and Oxa‐Spirocyclic Compounds Under Visible Light Irradiation

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
This review presents the visible‐light‐mediated photochemical reaction for the synthesis of aza, oxa, and aza–oxa spirocyclic compounds via photoinduced electron transfer (PET), hydrogen atom transfer (HAT), single‐electron transfer (SET), or energy transfer (EnT) pathways.
