Synthesis, Biological Evaluation, and Theoretical Study of Indenoquinolinylphosphine Oxide Derivatives as Topoisomerase 1 Inhibitors and Antiproliferative Agents

ChemMedChem, Volume 21, Issue 5, 13 March 2026.
The topoisomerase I inhibition and antiproliferative activities of phosphorated indenoquinoline derivatives were investigated. The target hybrid quinoline and tetrahydroquinoline compounds were synthesized via a two‐step Povarov‐type cycloaddition.

The Diarylprolinol Silyl Ethers: After 20 Years Still Opening New Doors in Asymmetric Catalysis

Angewandte Chemie, Volume 138, Issue 11, 9 March 2026.
Catalysis Rules! The year 2025 marks the 20th anniversary of diarylprolinol silyl ethers in asymmetric organocatalysis. During the first decade after their discovery, these catalysts have been established as one of the most versatile tools in aminocatalysis. Although now considered mature, recent years have witnessed renewed innovation.

Dynamic Covalent Polymeric Foams: En Route to a Sustainable Lightness

ChemSusChem, Volume 19, Issue 5, 13 March 2026.
Dynamic covalent polymer foams (DCPFs) combine lightweight cellular structures with adaptive polymer networks, enabling self‐healing, reprocessability, and recyclability. By integrating reversible covalent bonds into foam architectures, these materials open new pathways toward sustainable porous polymers within a circular materials economy.

Mild Generation of Highly Nucleophilic N‐Heterocyclic Carbene Boryl Anion From Neutral sp2–sp3 Diboron Reagents and Its Applications in Nucleophilic Borylation

Angewandte Chemie, Volume 138, Issue 11, 9 March 2026.
A less hindered and highly nucleophilic N‐heterocyclic carbene (NHC) boryl anion is generated at room temperature by reacting sp2–sp3 diboron reagent (NHC)BH2Bpin with KOtBu. This highly reactive anion demonstrates broad reactivity with various electrophiles, including those traditionally considered inert, enabling their efficient borylation.
