Total Synthesis of the Spirocyclic Bis‐Indole Alkaloid (−)‐Owerreine via a [4+2] Annulation

Angewandte Chemie, Volume 138, Issue 17, 20 April 2026.
The total synthesis of the bis‐indole alkaloid (−)‐owerreine has been accomplished by a diastereoselective [4+2] annulation between an enamine and an α,β−unsaturated indolenine precursor to form the 3‐spirocyclic tetrahydropyridine linkage of the natural product. DFT calculations allow an understanding of the mechanism of the key annulation.

NiH‐Catalyzed Enantioconvergent α‐Alkenylation of Carbonyl Compounds via Markovnikov Alkyne Hydronickellation

Angewandte Chemie, Volume 138, Issue 17, 20 April 2026.
A NiH‐catalyzed α‐alkenylation via Markovnikov hydronickellation of alkynes enables convenient access to α‐chrial β‐methylene carbonyl frameworks that are prevalent in biorelevant molecules. High regio‐ and enantioselectivities have been achieved with excellent functional group tolerance and applicability toward complex structures. The β‐methylene unit
