Part 1: The Direct Arylation of Azine N-Oxides with Aryl Triflates Part 2: The Site-Selective Direct Arylation of Substituted Indoles

, 2010
Part 1: The Direct Arylation of Azine N -Oxides with Aryl Triflates. Two sets of conditions for the palladium-catalyzed direct arylation of azine N-oxides with aryl triflates have been developed. Using palladium(II) acetate, a trialkylphosphine ligand, a

Advances in Unconventional and Sustainable Synthetic Approaches to Benzopyran Scaffolds

The Chemical Record, EarlyView.
This review provides a comprehensive and critical analysis of low‐impact synthetic methodologies reported in the last 8 years (2018–2026) for the construction of benzopyran‐derived scaffolds, such as coumarins, flavones, chromones, chromenes, and chromanes. The benzopyran scaffold is a versatile family of heterocycles found in a wide range of bioactive

Direct Arylation of Polycyclic Aromatic Hydrocarbons through Palladium Catalysis

, 2016
We have discovered that the combination of Pd(OAc)2/o-chloranil can catalyze the direct C–H bond arylation of polycyclic aromatic hydrocarbons (PAHs) with arylboroxins that occurs selectively at the K-region.

Trans‐resveratrol alleviates inflammation and improves skin barrier function via aryl hydrocarbon receptor pathway in human reconstructed epidermis

International Journal of Cosmetic Science, EarlyView.
In a cytokine‐challenged human epidermal model, trans‐resveratrol reduces inflammation (IL‐1α) and oxidative stress markers (CYP1A1, CYP1B1), while modulating the expression of barrier‐related genes (LOR, OCLN) and differentiation‐associated CASP14. This supports its role as a multifunctional active for sensitive and compromised skin.

Soft and Stretchable Thienopyrroledione‐Based Polymers via Direct Arylation

Advanced Electronic Materials
π‐conjugated polymers (CPs) that are concurrently soft and stretchable are needed for deformable electronics. Molecular‐level modification of indacenodithiophene (IDT) copolymers, a class of CPs that exhibit high hole mobilities (μhole), is an approach ...

Regioselective Diversification of Aminopyrazoles via Ir‐Catalyzed C─H Borylation

Advanced Synthesis &Catalysis, Volume 368, Issue 21, 3 November 2026.
Aminopyrazoles, an important bioactive pharmacophore, are typically accessed inefficiently through de novo syntheses that yield isomeric mixtures of 3‐ and 5‐substituted derivatives. To address this challenge, we have elaborated readily available 3‐ and 5‐aminopyrazole fragments using Ir C─H borylation, regioselectively furnishing boronates for ...
