Ullmann‐Type N‐Heteroarylation of Nitrogen Heterocycles Catalyzed by Heterogeneous CuNPs/HKUST‐1

open access: yesEcoEnergy, EarlyView.
A practical strategy for the direct synthesis of CuNPs/HKUST‐1 heterogeneous catalyst was developed and used for the catalyzing Ullmann‐type N‐arylation of N‐heterocycles with high yields, excellent recyclability, and low copper leaching. ABSTRACT Ullmann‐type C–N coupling is an essential reaction to construct functional nitrogen heterocycles, whereas ...

Auto‐Click Synthesis of a Copper(I)–N‐Heterocyclic Carbene Porous Organic Polymer and Its Transmetalation to Palladium(II) for Azide–Alkyne Cycloaddition and Cross‐Coupling Reactions

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
An azide‐functionalized Cu(I)–NHC complex acts as both a monomer and a catalyst in an auto‐click polymerization, yielding a Cu(I)–NHC polymer that can be transmetalated to Pd(II). The two materials catalyze copper‐catalyzed azide–alkyne cycloaddition, C–N/C–O coupling, and Suzuki–Miyaura reactions, while copper reloading restores activity.

Exploring the Anticancer Activity of Ruthenium(II)–Arene and Copper(I) Complexes Bearing N‐Heterocyclic Carbene Ligands Containing Azido, Pyridinium, and Ethisterone‐Derived Triazole Groups

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
A versatile library of backbone‐functionalized N‐heterocyclic carbene (NHC) ligands was developed and efficiently converted into Cu(I) and Ru(II) NHC complexes, demonstrating that ligand functionalization strongly modulates anticancer activity, with Cu(I)–NHC species showing potent and selective antiproliferative effects against ovarian and breast ...

Retro‐Hetero‐Michael Addition Strategies in Organic Synthesis

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
In this review, synthetic approaches to carbo‐ and heterocyclic compounds, including natural products, published in the last 15 years (2011–2025) which have either relied upon or included a retro‐hetero‐Michael addition step at any stage are discussed.

Diarylethene‐Containing Photoswitchable Analogues of Tubulysins—Design, Synthesis, Biological, and Structural Evaluation

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Diarylethene‐containing cyclic tubulysin analogues were designed, synthesized, and evaluated as light‐responsive cytotoxic agents. One analogue showed reversible photoswitching, photoregulated tubulin polymerization inhibition, and photoform‐dependent cytotoxicity.
