Benzyl Protection of Phenols under Neutral Conditions: Palladium-Catalyzed Benzylations of Phenols

, 2016
Benzyl protection of phenols under neutral conditions was achieved by using a Pd(η3-C3H5)Cp–DPEphos catalyst. The palladium catalyst efficiently converted aryl benzyl carbonates into benzyl-protected phenols through the decarboxylative etherification ...

Water‐Compatible SuFEx‐Active Diazonium Linchpin Platform for Rapid Modular Diversification and On‐DNA Functionalization

Advanced Functional Materials, EarlyView.
Sulfur fluoride exchange (SuFEx) is a powerful click platform, yet water‐compatible multifunctional linchpins remain elusive. Here, we report decagram‐scalable diazonium linchpins that enable rapid Pd‐catalyzed diversification and direct, catalyst‐free on‐DNA ligation in aqueous media.

Phenols and GABAA receptors: from structure and molecular mechanisms action to neuropsychiatric sequelae

Frontiers in Pharmacology
γ-Aminobutyric acid type A receptors (GABAARs) are members of the pentameric ligand-gated ion channel (pLGIC) family, which are widespread throughout the invertebrate and vertebrate central nervous system. GABAARs are engaged in short-term changes of the

Angular Phenozaxine Ethers as Potent Multi-microbial Targets Inhibitors: Design, Synthesis, and Molecular Docking Studies

Frontiers in Chemistry, 2017
The reaction of diaza-5H-benzo[a]phenoxazin-5-one and 5H-benzo[a]phenoxazin-5-one with various phenols catalyzed by Pd/t-BuXPhos/K3PO4 system gave previously unknown ether derivatives (7a–f and 8a–f) in good yields. UV-visible, FTIR, and 1H NMR data were

Coagulative Granular Hydrogels with an Enzyme Catalyzed Fibrin Network for Endogenous Tissue Regeneration

Advanced Healthcare Materials, EarlyView.
Coagulative granular hydrogels are composed of packed thrombin‐functionalized microgels that catalyze the conversion of fibrinogen into a secondary fibrin network, filling the interstitial voids. This bio‐inspired approach stabilizes the biomaterial to match the robustness of bulk hydrogels without compromising injectability, mimicking the initial ...
