Total Syntheses of Agelamadin F and (±)‐Tauroacidin A, Enabled by NaClO2‐Mediated Coupling Reactions of Oroidin and Amines

Chemistry – A European Journal, Volume 32, Issue 27, 17 July 2026.
Total syntheses of agelamadin F and (±)‐tauroacidin A were achieved by sodium chlorite (NaClO2)‐mediated oxidative C─N coupling. Nine C15–N–amino acid‐substituted oroidin derivatives were successfully prepared to demonstrate the applicability and versatility of this oxidative coupling reaction.

Overcrowded Alkene Photo‐Redox‐Switches Based on Quinolinium/Carbene Building Blocks

Angewandte Chemie International Edition, Volume 65, Issue 29, 13 July 2026.
A modular synthesis of a new class of photo‐ and redox‐switches is described based on the combination of quinolinium salts and carbenes. Photochemical switching allows to selectively switch between folded E/Z isomers, while electrochemical switching allows to change between neutral, radical cation and dicationic oxidation states, which are all isolable

A Modular Synthesis of Isoindole/Indolizine Hybrids via the 1,3‐Dipolar Cycloaddition of Pyridine‐Based Mesoionics with Benzyne

European Journal of Organic Chemistry, Volume 29, Issue 26, 13 July 2026.
An approach to prepare pyrido[2,1‐a]isoindoles via the cycloaddition of pyridine‐based 1,3‐dipoles and benzyne is described, offering modular access to a range of substituted products by systematic tuning of the dipole. A modular strategy for the synthesis of fused indolizine/isoindole hybrids, pyrido[2,1‐α]isoindoles, via cycloaddition of pyridine ...

A Proline‐Integrated Donor–Acceptor Fluorophore: Water‐Vapor‐Responsive Mechanochromic Luminescence and Latent Fingerprint Visualization

Advanced Optical Materials, Volume 14, Issue 25, 3 July 2026.
A proline‐integrated donor–acceptor fluorophore enables multifunctional luminescence through rational molecular design. Water‐vapor‐responsive mechanochromic luminescence (MCL) with circularly polarized luminescence (CPL) switching and efficient visualization of latent fingerprints (LFPs) are realized from this single small organic molecule.

Asymmetric α‐Alkylation With Activated and Unactivated Electrophiles by a Highly Productive and Recyclable Lewis Acid/Imidazolium Catalyst

Angewandte Chemie International Edition, Volume 65, Issue 27, 1 July 2026.
An air‐stable, easily prepared, bifunctional Cu(II)/imidazolium complex enables highly enantioselective α‐alkylation of 1,3‐dicarbonyls with outstanding productivity (TON up to 1740). Highlights include broad electrophile scope spanning π‐activated and nonactivated reagents, stereo‐retentive allylation, simple catalyst synthesis, and efficient catalyst

Structure–Function Study of a Family of Membrane‐Targeted Azobenzene Phototransducers With Bacillus subtilis

ChemPhotoChem, Volume 10, Issue 7, July 2026.
Membrane‐targeted amphiphilic azobenzenes act as phototransducers to enable light‐driven modulation of various biological outcomes in bacteria. We find that systematic variation of cationic charge density and molecular asymmetry of these azobenzene photoswitches reveals how molecular design governs bacterial cell membrane association, photophysical ...
