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

3D‐Printed Geopolymer as a Basic Heterogeneous Catalyst for the Synthesis of α‐Cyanoacrylates Through the Knoevenagel Condensation

European Journal of Organic Chemistry, Volume 29, Issue 16, 25 April 2026.
3D‐printed geopolymers are presented as efficient and reusable heterogeneous catalysts for the Knoevenagel condensation. Under mild and green conditions, they promote the high‐yield synthesis of diverse α‐cyanoacrylates with remarkable stability and scalability.

Enantioselectivity in Transition Metal Catalyzed Propargylic Substitution Reactions: A Theoretical Perspective

Chemistry – A European Journal, Volume 32, Issue 15, 22 April 2026.
Recent theoretical efforts to elucidate the origin of enantioselectivity in transition metal‐catalyzed propargylic substitution reactions are highlighted in this review. ABSTRACT In recent years, asymmetric catalytic propargylic substitution reactions have undergone remarkable development, enabling the construction of chiral carbon centers adjacent to ...
