Carbamate‐Directed peri‐CH Alkynylation: Application to the Synthesis of Zethrenes and Pyranthrenes
ChemistryEurope, Volume 4, Issue 5, May 2026.The Rh(III)‐catalyzed regioselective alkynylation of 1‐pyrenyl and 1‐naphthyl carbamates with bromoacetylenes enables the selective installation of an alkyne at the peri position of readily accessible amino‐substituted polycyclic aromatic hydrocarbons (PAHs).

Quantifying Carboxylate Burial in Synthetic Hydrophobic Pockets in Water
ChemistryEurope, Volume 4, Issue 5, May 2026.How “buried” is a buried ion? Double mutant cycles quantify the cost of placing a carboxylate within a deep aromatic calix[4]pyrrole pocket in water. The penalty is only +1.3 to +3.0 kcal·mol−1 because water penetrates through cracks and the portal, creating a wet, high‐dielectric microenvironment.

MGL‐Based Drug Conjugate: A Novel Glycan‐Targeting Strategy for Potential Precision Cancer Therapy
ChemistryEurope, Volume 4, Issue 5, May 2026.An engineered macrophage galactose‐type lectin (MGL)‐based conjugate (mMGL‐vcMMAE), incorporating an exposed cysteine for site‐specific drug linkage, preserves stability, binding profile, and affinity of the native MGL carbohydrate recognition domain. It also selectively targets Tn/STn‐expressing cancer cells and shows recognition of colorectal cancer ...

One-pot cross-enyne metathesis (CEYM)–Diels–Alder reaction of gem-difluoropropargylic alkynes
Beilstein Journal of Organic Chemistry, 2013 Propargylic difluorides 1 were used as starting substrates in a combination of cross-enyne metathesis and Diels–Alder reactions. Thus, the reaction of 1 with ethylene in the presence of 2nd generation Hoveyda–Grubbs catalyst generates a diene moiety ...

Magnetism for the Quantification of Sorption in Porous Materials From Liquid Media
Chemistry–Methods, Volume 6, Issue 5, May 2026.This adsorption quantification technique uses external magnetic fields and a magnetic holder to measure mass changes during adsorption, making it universally applicable to any adsorbate. Unlike standard methods, it requires calibration only for the adsorbent rather than for every analyte.

British Journal of Pharmacology, Volume 183, Issue 9, Page 1993-2008, May 2026.Abstract Background and Purpose Immune tolerance prevents inflammation and autoimmunity, with dendritic cells (DCs) playing a key role. Reprogramming DCs towards a tolerogenic state represents a promising therapeutic strategy. Sulforaphane (SFN) has known immunomodulatory effects, but its clinical application is limited by poor stability and ...

European Journal of Organic Chemistry, Volume 29, Issue 16, 25 April 2026.The formation of triplet Ni(II) complexes by activation of bromoalkenes with alkyl‐ or boryl Ni(I) is key to control the outcome of the reductive cross‐coupling of bromoalkanes precluding the formation of alkylboronates. We present a mechanistic study on the Ni‐catalyzed cross‐coupling reaction of bromoalkanes with diboron compounds as reductants.

Silyl Rearrangements in Gold‐Catalyzed Transformations
European Journal of Organic Chemistry, Volume 29, Issue 15, 22 April 2026.The synergy between the exceptional ability of gold catalysts to activate unsaturated substrates and the inherent tendency of organosilicon reagents to undergo silyl‐group rearrangements has unlocked a range of novel transformations, enabling access to otherwise challenging molecular architectures.
