Recent Advances in Isatin–Thiazole Hybrids: Synthesis, Structural Design, and Biological Application

Chemistry &Biodiversity, EarlyView.
ABSTRACT Isatin–thiazole hybrids are considered privileged chemical scaffolds due to their broad spectrum of pharmacological properties, making them attractive candidates for drug development. As a result, isatin–thiazole derivatives have emerged as a prominent class of hybrid heterocycles and have been the focus of extensive research in recent years ...

Enhancing Deoxygenation of a Biopetroleum Model Compound Using Mesoporous Beta Zeolite

ChemCatChem, EarlyView.
Beta zeolite with 13 SAR is modified by alkaline and acidalkaline treatments to generate mesoporosity and improve accessibility of bulky molecules. Characterization confirms enhanced silicon removal and mesopore volume. In catalytic deoxygenation of a lignocellulosic‐derived model compound, treated BEA shows reduced oxygenates, higher hydrocarbon yield,

Mono‐Amination of Methyl‐α‐d‐glucoside via Borrowing Hydrogen with Recyclable Ru/C

ChemCatChem, EarlyView.
Mono‐amination of methyl‐α‐d‐glucoside in the presence of a recyclable Ru based catalyst: effect of the nature of the atmosphere. Abstract This study presents a highly efficient and sustainable method for the mono‐amination of unprotected sugar derivatives using a commercially available Ru/C heterogeneous catalyst under borrowing hydrogen (BH ...

Selective Imine Synthesis by Acceptorless Dehydrogenative Coupling of Alcohols and Amines via Cooperative Catalysis of Basic‐Polyoxometalate‐Decorated Ag Nanoparticles on Al2O3

ChemCatChem, EarlyView.
Multi‐functional catalysts, POM‐decorated Ag nanoparticles supported on Al2O3 (POM‐Ag/Al2O3), were developed for the selective acceptorless dehydrogenative coupling of alcohols and amines to imines. The catalyst features tri‐functional activity: basic [Nb6O19]8‐ on Ag enables oxidative dehydrogenation, while Al2O3 provides Lewis acid sites for ...
