A Multicomponent Electrosynthesis of 1,5-Disubstituted and 1‑Aryl 1,2,4-Triazoles

open access: yes, 2018
A novel electrochemical route has been developed for the synthesis of 1,5-disubstituted and 1-aryl 1,2,4-triazoles from aryl hydrazines, paraformaldehyde, NH4OAc, and alcohols.

1,2,3-Triazole N(2)-chelated C–S coupling: Access to ortho methylthiolated 1,2,3-triazoles

open access: yes, 2019
CuF2-mediated selective C-S coupling of 1,4-disubstituted 1,2,3-triazole halides using the widely available DMSO as the methylthiolation reagent were achieved through the chelation of N(2) atom in triazole ring. The ortho- C-halogen bond in N(1) aryl was

A Portal‐Preorganized Cucurbit[7]uril‐Ruthenium Conjugate Enables Motif‐Selective Protein Sensing

open access: yesAngewandte Chemie International Edition, EarlyView.
Reprogramming cucurbit[7]uril (CB7) recognition through portal engineering transforms an optically silent host into a motif‐selective photoluminescent receptor. The portal‐preorganized CB7‐Rubpy conjugate directly reports changes in aromatic motif accessibility, enabling optical sensing of protein misfolding and refolding.

STUDY OF THE PROTONATION OF 1, 2, 4-TRIAZOLE. DFT CALCULATIONS

open access: yesVìsnik Dnìpropetrovsʹkogo unìversitetu. Serìâ Hìmìâ
У цій роботі досліджена реакція між 1,2,4-тріазолом і хлоридною кислотою (HCl) з метою синтезу протонованого 1,2,4-тріазолу (TAH+). Ми використовували розрахунки теорії функціоналу густини (DFT), щоб отримати уявлення про структурний аналіз молекули. Кілька дескрипторів реакційної здатності, включаючи спорідненість до електрона, різниця енергій HOMO ...

Click‐to‐Release Reactivity of Quaternary Anilinium Tetrazines Enables Cascade Assembly of Multifunctional Biomolecular Scaffolds

open access: yesAngewandte Chemie International Edition, EarlyView.
Click chemistry has evolved from making covalent connections to also breaking bonds. Here, a cascade assembly is reported that combines these maneuvers to build multifunctional biomolecular scaffolds in a modular one‐pot reaction. The unifying azide release‐tetrazine hub clicks with a trans‐cyclooctene tag, rapidly liberates N,N‐dimethylaniline to ...

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

open access: yesBulletin 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 ...
