European Journal of Organic Chemistry, EarlyView.A Pd(0)‐catalyzed cyclotrimerization of benzoCOTynes to form tri(benzo[8]annulenes) was developed. Three distinct isomers were isolated and structurally characterized by single‐crystal X‐ray diffraction. Ligand modulation proved crucial for enhancing regioselectivity: P(4‐OMePh), and (S)‐tBu‐Phox promoted the formation of the symmetric isomers.

Metal‐Free Electrophilic Borylative Cyclizations of Alkynes
The Chemical Record, EarlyView.Metal‐free borylative cyclizations based on electrophilic alkyne activation by boron Lewis acids provide efficient access to borylated hetero‐ and carbocycles. Early studies using B(C6F5)3 displayed limited scope and application, whereas recent ClBcat‐ and BCl3‐based methods enable mild CB and CC/CX bond formation for the synthesis of cycles ...

Dendrimeric Antigens for Passive Mast Cell Activation in the Evaluation of Amoxicillin Allergy
Allergy, EarlyView.DeAns with defined nanoscale structure reveal that conjugate size and determinant density govern IgE‐mediated effector‐cell activation in AX allergy. All DeAn generations bind to sIgE in inhibition immunoassay, but only larger DeAns trigger FcεRI‐dependent responses in mouse MC, huRBL‐2H3, and LUVA cells.

Exploring 6‐Hydroxy‐3‐Aryl/Heteroarylcoumarins as Promising Candidates Against Trypanosoma cruzi
ChemMedChem, Volume 21, Issue 9, 14 May 2026.New therapies are urgently needed for Chagas disease, and screening of 6‐hydroxy‐3‐aryl/heteroarylcoumarin derivatives identified highly selective compounds with potent activity against T. cruzi. In particular, derivative 1f showed submicromolar trypomastigote potency, dual‐stage activity, and inhibition of amastigote‐to‐trypomastigote differentiation,

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.Heterogeneous‐catalyzed selective and versatile hydrogenative functionalizations of phthalimides have been developed for the first time. By using a solid nanocomposite formed by [Ag/Al2O3] material in combination with [H‐BETA] zeolite as cocatalyst, a broad range of 3‐functionalized isoindolinones have been accesed in one‐pot from phthalimides, H2 and ...
