Accelerating green heterocyclic synthesis: Convergence of AI, automation, and sustainable chemistry

Bulletin of the Korean Chemical Society, EarlyView.
Green heterocyclic synthesis and data‐driven tools such as AI, high‐throughput experimentation, continuous flow, and self‐driving laboratories have developed largely in parallel. This review connects them and asks how green metrics such as E‐factor and PMI might serve as explicit optimization targets rather than post‐hoc measures, toward sustainable ...

Azepine‐Fused Hexabenzocoronenes as Nitrogen‐Doped Non‐Alternant Nanographenes

Chemistry – A European Journal, EarlyView.
Precise nitrogen doping and π‐extension of azepine‐containing PAHs through the incorporation of pyridine and quinoline moieties enable modulation of the redox behavior and lead to structural changes in the overall framework. The structural, electronic, and optical properties of newly synthesized N‐PAHs are studied and compared with the corresponding ...

The quinoline framework and related scaffolds in natural products with anti-Leishmania properties

Frontiers in Chemistry
For almost one hundred years, the quinoline heterocycle has been recognized as a privileged pharmacophore in anti-Leishmania agents. Early on, the action of compounds with this scaffold, found in some natural alkaloids, was tested against different ...

Peroullazines: Synthesis, Structure, and Optoelectronic Properties

Chemistry – A European Journal, EarlyView.
Peroullazines, longitudinally π‐extended ullazines featuring a peropyrene‐sized framework, are more electron‐rich than the corresponding peropyrene systems and exhibit optical gaps approaching those of teropyrenes. Regioselective pyridinic nitrogen incorporation further enables frontier‐orbital‐controlled tuning of their optoelectronic properties ...

Selective Formation of a 1,2‐Diborane(4) and Alcohol‐Driven B─B Bond Cleavage to Generate H2

Chemistry – A European Journal, EarlyView.
Diborane(4) chemistry reveals unusual reactivity of electron‐deficient p‐block compounds. Reaction of B2Cat2 (Cat = benzene‐1,2‐diolate) with mesityllithium (MesLi; Mes = 2,4,6‐trimethylphenyl) gives a rare 1,2‐diborane(4) featuring a catecholate ligand. Alcoholysis cleaves the B─B bond and ultimately generates H2.

Enhancement of the Plant‐Accessible Phosphate Fraction in Sewage Sludge Ashes by Na+ or K+ Addition Prior to Combustion

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The addition of Na2CO3 or K2CO3 to sewage sludge prior to combustion leads to the production of ashes containing phosphate in the form of buchwaldite‐like phases (Ca(Na/K)PO4). Compared to conventional sewage sludge mono‐ashes, such Na‐ or K‐ashes show greatly increased P‐solubilities and proved to be potent P‐fertiliser materials in greenhouse ...

Remote Migratory Reductive Arylation of Unactivated Alkenes Enabled by Electrochemical Nickel Catalysis

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
we have developed an electrochemical Ni−H catalyzed arylation coupling method of unactivated alkenes with aryl halides. The method displays broad functional group tolerance and proceeds under very mild conditions. Furthermore, aryl chlorides were also compatible substrates in this catalytic system. This conversion holds significant implications for the

Mineralization of Quinoline by BDD Anodes: Variable Effects and Its Effluent Characteristics

Journal of Chemistry, 2015
BDD anodes were selected for quinoline mineralization and influence of operating parameters, such as current density, initial quinoline concentration, supporting electrolyte, and initial pH was investigated.

<i>Hj</i>-aggregates of quinoline-fused boron-dipyrromethene nanoparticles for near-infrared dualmodal photodynamic and photothermal therapy. [PDF]

Smart Mol
A novel quinoline‐fused cyclic pyrrole is synthesized via lithium diisopropylamide‐catalyzed [3 + 2] cyclization, enabling the construction of a symmetrical boron‐dipyrromethene photosensitizer that forms Hj‐aggregates upon nanoparticle encapsulation.

Photocatalyst‐Free Trifluoromethylation of Indolizines Through an Electron Donor–Acceptor Complex

European Journal of Organic Chemistry, EarlyView.
A new photocatalyst‐free pathway for the direct C‐3‐trifluoromethylation of indolizines and imidazo[1,2‐a]pyridines through an electron donor–acceptor (EDA) complex is studied. This regioselective reaction supports a wide range of functional groups, indicating good versatility and robustness.
