Diastereoselective Synthesis of Highly Substituted Methylene Cyclobutanes by Pd Catalysis
European Journal of Organic Chemistry, EarlyView.A chemo‐ and diastereoselective palladium‐catalyzed intramolecular coupling/cyclization of borylated 1,5‐dienes, readily accessible by allene allylboration, with iodoarenes enables the synthesis of highly substituted methylene cyclobutanes. The method exhibits broad scope, high functional group tolerance, and complete enantiospecificity.

Nanographene‐Based van der Waals Organic Framework With Permanent Porosity
Angewandte Chemie, Volume 138, Issue 27, 1 July 2026.Unlocking record‐breaking porosity in a supramolecular organic framework (SOF). Through the strategic design of a C3‐symmetric nanographene, a robust supramolecular framework is achieved via exclusively weak van der Waals forces. This metal‐free scaffold reaches a benchmark BET surface area of 1108 m2 g−1 –the highest to date for this class–combining ...

Influence of the cis/trans configuration on the supramolecular aggregation of aryltriazoles
Beilstein Journal of Organic Chemistry, 2019 The ability of trans- and cis-1,2-glucopyranosyl and cyclohexyl ditriazoles, synthesized by CuAAC "click" chemistry, to form gels was studied, their physical properties determined, and the self-aggregation behavior investigated by SEM, X-ray, and EDC ...

Pest Management Science, EarlyView.The bio‐guided phytochemical study resulted in the new compound 17‐epi‐melianodiol. The compound eliminated 100% of Aedes aegypti larvae at 100 ppm, causing pronounced morphological changes, cuticular damage, and extensive vacuolization. Abstract BACKGROUND In Brazil, Aedes aegypti is the primary vector of arboviruses such as dengue, chikungunya ...

Angewandte Chemie, Volume 138, Issue 27, 1 July 2026.A deep‐red‐excited osmium(II) photosensitizer (Os2) induces immunogenic cell death (ICD) under 740 nm irradiation and triggers robust anti‐tumor immune responses both in vitro and in vivo. ABSTRACT Immunogenic cell death (ICD), which converts tumor cells into their own vaccine, plays a pivotal role in the development of novel anticancer therapies. Here,

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.
