Recent advances in photocatalytic hydrogen peroxide production

open access: yesPhotoMat, EarlyView., 2023
We classify the representative photocatalytic materials for photosynthesis of hydrogen peroxide (H2O2) in recent years and discuss the related modification methods in detail, providing inspiration and insights for the future design of photocatalysts for H2O2 production.

Stable BF2 Boracycles as Versatile Reagents for Selective Ortho C–H Functionalization

open access: yesAngewandte Chemie, EarlyView.
We report a robust, metal‐free and scalable synthesis of stable BF2 boracycles via directed ortho CH borylation, delivering isolable, shelf‐stable reagents without chromatographic purification. These BF2 boracycles exhibit unique and tunable reactivity, enabling highly selective ipso‐functionalization across a broad range of transformations.

Doxorubicin‐Loaded Metal–Organic Framework for Ferroptosis‐Enhanced Chemotherapy Through Sustained Zn Release and Glutathione Peroxidase Downregulation

open access: yesAdvanced Healthcare Materials, EarlyView.
A robust zinc‐based metal–organic framework (ZnMOF) enables dual functions of doxorubicin delivery and sustained Zn2+ release to trigger ferroptosis‐enhnaced chemotherapy. DOX@ZnMOF effectively depletes intracellular glutathione, suppresses GPX4, and elevates reactive oxygen species, leading to efficient oxidative DNA damage and apoptosis.

Polystyrene Nanocomposites Based on Quinolinium and Pyridinium Surfactants [PDF]

open access: yes, 2006
In this paper pyridine and quinoline-containing salts were employed to modify montmorillonite. TGA analysis shows that the quinolinium modified clay has a higher thermal stability than the pyridinium modified clay.

Design and Utilization of Stable Hydrofluoroolefin‐Based Trifluoropropynyl Surrogate for Sonogashira Coupling

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
A novel methodology for the construction of aromatic and heteroaromatic trifluoropropynyl derivatives has been developed. The new protocol is based on a tandem Sonogashira cross‐coupling reaction between a bench‐stable trifluoropropynyl carbinol reagent, generated from the commercially available and inexpensive hydrofluoroolefin‐1234yf gas, and (hetero)

Total Synthesis of (+)‐Melonine and (+)‐N4‐Oxy Melonine Enabled by an Intramolecular Alkene Diamination Reaction

open access: yesAngewandte Chemie, EarlyView.
A complexity‐generating intramolecular alkene diamination constitutes the pivotal step in the enantioselective synthesis of the title natural products featuring a strained, cage‐like pentacyclic architecture. Abstract Among more than four thousand monoterpene indole alkaloids (MIAs) isolated to date, only a few feature a 2,2,3‐trisubstituted indoline ...

Vm–MSI: a Vancomycin–Antimicrobial Peptide Conjugate Combating Resistant Bacteria and Broadening the Antimicrobial Spectrum

open access: yesAdvanced Science, EarlyView.
A series of vancomycin‐antimicrobial peptide conjugates is synthesized and evaluated to identify the optimal combination. Vm‐MSI, selected from multiple candidates, exhibited potent activity against vancomycin‐resistant and Gram‐negative bacteria by disrupting membranes and inducing oxidative stress, thereby expanding vancomycin's antibacterial ...

Current developments of metal- and metalloid-based quinoline compounds as leishmanicidal agents

open access: yesFrontiers in Chemistry
The quinoline moiety represents an important scaffold for the development of leishmanicidal agents. In particular, its hybridization with metal/metalloids has generated highly active compounds that are, in some cases, highly selective against ...
