α-Chloroketones enabled Rh(III)-catalyzed enantioselective C–H [4+2] annulation of sulfoximines under mild and redox-neutral conditions

Green Synthesis and Catalysis
Taking advantage of facilely available α-chloroketones as C(sp3)-based electrophilic partners and oxidized alkyne equivalents, we here present a novel CpxRh(III)-catalyzed enantioselective C–H [4 ​+ ​2] annulation of sulfoximines under mild and redox ...

Pesticide use in integrated pest and pollinator management framework to protect pollinator health

Pest Management Science, Volume 81, Issue 4, Page 1691-1696, April 2025.
Integrated pest management (IPM) emphasizes non‐chemical methods, with pesticides as a last resort, while integrated pest and pollinator management (IPPM) integrates pollinator health into pest control strategies. Abstract Agricultural pesticides have historically been a critical tool in controlling pests and diseases, preventing widespread suffering ...

Synthesis of N-(1H)-tetrazole sulfoximines

, 2007
N-(1H)-Tetrazole sulfoximines are readily available by addition of sodium azide to the corresponding N-cyano derivatives in the presence of ZnBr2. The use of these N-(1H)-tetrazoles as intermediates in the synthesis of other N-heterocyclic sulfoximines ...

Selective excitatory effects of γ‐glutamyl‐glycine, a glutathione metabolite, on GluN1 NMDA and mGlu5 receptors impacting synaptic plasticity

British Journal of Pharmacology, EarlyView.
Background and Purpose Gamma‐glutamyl dipeptides are essentially produced after glutathione (GSH) degradation. While several γ‐glutamyl dipeptides have been detected in different organs and body fluids, their biological activity remains elusive. This is the case for γ‐Glutamyl‐Glycine (γ‐Glu‐Gly) which has been found in different brain areas.

Reactive oxygen species, antioxidants and the regulation of plant development

The FEBS Journal, EarlyView.
The regulation of axillary bud outgrowth by the interplay between phytohormone and redox signals. Axillary bud outgrowth is regulated by cellular energy status and the balance between phytohormones, notably abscisic acid (ABA) and gibberellic acid (GA).

Thiolane Sulfoximines as Azide Surrogates for Quinolyl Nitrenes: Photochemical Access to Ortho‐Diaminoquinolines

Advanced Synthesis &Catalysis, Volume 368, Issue 21, 3 November 2026.
Thiolane sulfoximines provide practical and safer surrogates for hazardous azides in nitrene photochemistry, enabling direct access to 7,8‐diaminoquinolines and fused δ‐lactams. DFT calculations support the reaction mechanism and rationalize product selectivity.
