Synthesis of Benzopyran Atropisomers via Electrophilic Halogenation
European Journal of Organic Chemistry, EarlyView.We report a halogenation‐based method for the synthesis of axially chiral benzopyrans, tolerating diverse substituents and halogens (Br, Cl, and I). A double bromination gives bisbenzopyrans with two stereogenic axes. Preliminary enantioselective conditions yield benzopyran atropisomer with up to 56% ee.

Journal of Applied Toxicology, EarlyView.ABSTRACT Bisphenol A (BPA) is increasingly replaced by structural analogs, yet their safety remains insufficiently characterized. This study investigated whether BPA and selected analogs, bisphenol AF (BPAF), bisphenol AP (BPAP), bisphenol P (BPP), and bisphenol E (BPE), induce cytotoxicity through activation of endoplasmic reticulum (ER) stress and ...

Discovery and Biosynthesis of the Novel Glycotetrapeptide Antibiotic Biffamycin A
Angewandte Chemie, Volume 138, Issue 26, 22 June 2026.Genetic de‐regulation of a silent biosynthetic pathway allowed isolation and characterisation of a novel glycopeptide antibiotic named biffamycin A, which harbours unprecedented 5‐chloro‐4‐methoxy tryptophan and 3R‐hydroxy(α‐D‐mannoysl)‐D‐lysine moieties and is bioactive against MRSA and VRSA.

Effect of Halogenation Treatment to Solder on Anodic Soldering [PDF]
The effect of the halogenation treatment of tin based solder on the wettability of tin based solder to glass was examined, and that treatment was applied to anodic soldering - soldering of glass utilizing the principle of anodic bonding. The halogenation

Binuclear Copper‐Dependent Oxidative Enzymes Involved in Fungal Natural Product Modifications
Journal of the Chinese Chemical Society, EarlyView.This article summarizes recent biochemical characterizations of a new enzyme family named by the authors as binuclear copper‐dependent oxidative enzymes (BiNCOs). Found in fungal natural product biosynthesis, BiNCOs catalyze diverse CH functionalization reactions, including C(sp3)H halogenation, C(sp3)H hydroxylation, C(sp3)O macrocyclization, and ...
