Characterization of Grape Cane Stilbenoids and Their Photo‐Degradation Products by HPLC‐DAD Coupled With Trapped Ion Mobility Spectrometry and High‐Resolution Tandem Mass Spectrometry

Rapid Communications in Mass Spectrometry, Volume 40, Issue 15, 15 August 2026.
ABSTRACT Rationale Bioactive (E)‐stilbenoids in vine extracts are prone to light‐induced transformation into the respective (Z)‐isomers and further degradation products, often resulting in a loss of bioactivity. We sought to study stilbenoid degradation beyond that of the well‐researched resveratrol due to the high diversity of stilbenoids in nature ...

Benzofuranyl Esters: Synthesis, Crystal Structure Determination, Antimicrobial and Antioxidant Activities

Molecules, 2015
A series of five new 2‐(1‐benzofuran‐2‐yl)‐2‐oxoethyl 4-(un/substituted)benzoates 4(a–e), with the general formula of C8H5O(C=O)CH2O(C=O)C6H4X, X = H, Cl, CH3, OCH3 or NO2, was synthesized in high purity and good yield under mild conditions.

Accessing Heterocycle‐Containing Borazine Frameworks via C−H Functionalization Reactions of Heterocycles

European Journal of Organic Chemistry, Volume 29, Issue 29, 7 August 2026.
A Pd/Cu cooperative catalytic system enables the direct C–H functionalization of a diverse range of five‐membered and benzo‐fused heterocycles with iodinated hexaarylborazines, providing efficient access to previously inaccessible heterocycle‐functionalized borazines.

Three Component Thio‐ and Carboboration of Alkynes: A Modular Route to Functionalised Bicyclic Boronates

Angewandte Chemie, Volume 138, Issue 30, 20 July 2026.
Three‐component thio‐ and carbo‐boration reactions to form functionalised benzoxaborinines and benzazaborinines are reported. The nucleophile scope includes thioethers, thiols, and (hetero)arenes. Mechanistic studies revealed a disparity between thioboration using thioethers and using thiols.

Pd‐Catalyzed Direct Access to 2‐Substituted (Aza)benzo[b]furans via Cascade Reactions Under “On‐Water” Conditions

Advanced Synthesis &Catalysis, Volume 368, Issue 15, 1 August 2026.
An “on‐water” scalable Pd‐catalyzed heteroannulation delivers benzofurans and furopyridines at ultralow catalyst loadings (down to 0.005 mol%), providing products essentially free of palladium residues. In addition to a broad substrate scope (aryl, alkenyl, and alkyl alkynes with o‐iodophenols or 2‐iodo‐3‐hydroxypyridines), this protocol enables a new ...

Unlocking Stereodefined Olefins by Z‐Selective Transition Metals‐catalyzed C−H Activations

ChemCatChem, Volume 18, Issue 15, 14 August 2026.
The synthesis of Z‐olefins is an important challenge in synthetic organic chemistry. Within this review, we report a comprehensive overview of transition metals‐catalyzed Z‐selective C–H activations of (hetero)arenes for the synthesis of stereodefined olefins.

Diastereoselective Copper‐Catalyzed Defluorosilylation of Pentafluoroethyl Alkenes to Access Polyfluorinated Allylsilanes

Chinese Journal of Chemistry, Volume 44, Issue 15, Page 2587-2592, 1 August 2026.
Under copper(I) catalysis, pentafluoroethylated alkenes can undergo smooth defluorosilylation to generate novel polyfluorinated products. The reaction exhibits high levels of diastereoselectivities for obtaining multisubstituted allylsilanes with control of the double bond geometry.
