1, 2, 3-Triazole appended L-ascorbic acid with antioxidant properties
, 2016 Since the discovery of vitamin C, the number of its known biological functions is continually expanding. Various pyrimidines and purines containing L-ascorbic acid exhibited significant antiproliferative effects against malignant human tumour cell lines.1 Vitamin C is a biologically significant reducing agent due to its 1-oxo-2- ene-2, 3-diol ...

Angewandte 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
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 ...

Mild C─F Activation of Azido(per)Fluoroalkanes
Chemistry – A European Journal, EarlyView.Mild and selective activation of C(sp3)–F bonds in azido(per)fluoroalkanes using thiolates was developed, leading to novel functionalized azides. The reaction is initiated by nucleophilic attack of the sulfur atom to the terminal nitrogen of the azido group, followed by fluoride ion elimination.

Chiral Pyrazolinylidene Complexes for Asymmetric Catalysis
Chemistry – A European Journal, EarlyView.The synthesis and application of pyrazolin‐5‐ylidene NHC chiral‐at‐ruthenium catalysts is reported. The strong donating pyrazolin‐5‐ylidene ligands led to highly electron rich ruthenium complexes, which showed excellent catalytic activity and enantioselectivity in the intramolecular aziridination of an alkene.

Chemistry – A European Journal, EarlyView.Five heteroleptic iridium(III) complexes bearing cyclometalated 2,4‐diphenylpyridinato ligands were synthesized and their electrochemiluminescence (ECL) investigated. Two different coreactants were evaluated: tri‐n‐propylamine and benzoyl peroxide under anodic and cathodic potentials, respectively.
