Characterisation of Sex Pheromone and Genetic Strain in Rachiplusia nu (Lepidoptera: Noctuidae) Populations Across Brazil

Journal of Applied Entomology, Volume 150, Issue 6, Page 791-802, July 2026.
ABSTRACT Rachiplusia nu, known as the sunflower looper (SFL) and belonging to the Plusiinae subfamily, is a major defoliator of soybeans, sunflowers and other horticultural crops across southern South America. This species has recently expanded to central and northern regions of Brazil, becoming a key soybean pest.

Redox‐Active Guanidines

ChemElectroChem, Volume 13, Issue 12, 17 June 2026.
Redox‐active guanidines, comprising guanidino‐functionalized aromatics (GFAs) and redox‐active urea azines (RAAs), are electron donors and strong Lewis and Brønsted bases that are used in several applications. They act as redox‐active ligands in bistable coordination compounds and as reagents in dehydrogenative coupling reactions and proton‐coupled ...

Design and Synthesis of Pyrimidino[4,5‐d]Pyrimidine‐Based Compounds as Potent B‐RAF V600E Inhibitors

ChemMedChem, Volume 21, Issue 11, 15 June 2026.
Novel pyrimido[4,5‐d]pyrimidine‐based inhibitors selectively target B‐RAF V600E with nanomolar affinity and adopt distinct type‐II binding modes. Complementary cellular profiling reveals highly active analogs, underscoring the versatility of this chemotype and establishing it as a promising scaffold for the development of next‐generation kinase ...

Iridium Complexes of a Triazole‐Derived Pincer Ligand: Synthesis, Reactivity, and Transfer Dehydrogenation Catalysis

Chemistry – A European Journal, Volume 32, Issue 22, 9 June 2026.
Ir pincer complexes bearing a triazole architecture in the pincer backbone and O‐ancillary chelating ligands are presented. These were employed in the catalytic transfer dehydrogenation of alkanes as well as of saturated heterocycles. Reactivity of these complexes with silver salts and Lewis acids produced various cationic iridium complexes.

Lighting the Path to Cyclic Phosphonamides via Halogen‐Bond Electron Donor–Acceptor Activation

Advanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.
Cyclic phosphinamides are valuable scaffolds for optoelectronic applications, yet remain difficult to access with existing methods. Here, we highlight a mild and straightforward visible light‐driven strategy that enables the formation of cyclic phosphinamides and thiophosphinamides.

Enantioselective Tandem Povarov/Urech–Read Reaction for the Synthesis of Dihydroquinoline/Hydantoin Hybrids

Advanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.
Herein, an organocatalytic asymmetric synthesis of dihydroquinoline/hydantoin hybrids is described. The synthetic protocol involves a tandem reaction comprising a phosphoric acid–catalyzed initial Povarov dimerization of in situ generated imine/enamine mixtures under tautomeric equilibrium, followed by a Urech–Read reaction of the 1,2‐dihydroquinoline ...
