Effects of Cyclopentadienyl Ligand Structure on Rhodium(III)‐Catalyzed Ortho‐C─H Arylation of Aryl Ketones

European Journal of Organic Chemistry, EarlyView.
A tailored, electron‐rich, anisotropic cyclopentadienyl ligand enables rhodium(III)‐catalyzed ortho arylation of aryl ketones at 80 °C using readily available arylboronic acid pinacol esters. Direct use of a cationic catalyst promotes binding of the weak ketone directing group, while scope and competition experiments reveal how ketone electronics and ...

Stabilization Strategies for Catechins and Epicatechins: Recent Advances

Food Chemistry International, EarlyView.
Oxidation, epimerization, polymerization, and hydrolysis, driven by heat, pH, and oxygen, are pathways. Nano‐/microencapsulation maintains integrity with 70%–95% efficiency; biopolymer nanoparticles, starch/polysaccharide nanocarriers improve stability and dispersion. Lipid nanocarriers enhance bioavailability but raise oxidation risk.

Palladium‐Catalyzed Heck‐Type Double Arylation of 1,2‐Dihydropyridines

Helvetica Chimica Acta, EarlyView.
A Pd‐catalyzed Heck‐type double arylation of 1,2‐dihydropyridines enables concise access to 2‐substituted 3,6‐diarylated scaffolds with high site‐ and regioselectivity. ABSTRACT We report a site‐ and regioselective Heck‐type double arylation of substituted 1,2‐dihydropyridines.

Synthesis of Microbial‐Derived Octadecanoids

Lipids, EarlyView.
C18‐carbon containing dietary polyunsaturated fatty acids (e.g., linoleic acid, α‐linolenic acid, and γ‐linolenic acid) are metabolized by bacteria in the gut into oxygenated lipid mediators termed octadecanoids. To study the biological function of these compounds, we report here the chemical synthesis of multiple octadecanoids.

Main‐chain polyfullerenes: Taking fullerene to the next dimension

Polymer International, EarlyView.
This short review appraises main‐chain polyfullerenes. Their slow development over 30 years has suddenly boomed with a rapid growth due to exciting developments in solar energy. Abstract This mini‐review gives an overview of the development, chemistry, properties and applications of main‐chain polyfullerenes.
