Synthesis of Cyclohexanone Oxime from Cyclohexanone and Ammonia.

Journal of The Japan Petroleum Institute, 1999
シクロヘキサノンとアンモニアのみを原料とするシクロヘキサノンオキシムの合成を検討した結果, Na-ZSM-5が高い活性を示すことを見い出した。この触媒の活性サイトは触媒上の塩基点であると考えられる。主な副生成物は, アルドール脱水縮合反応を経由して生成するピリジンの誘導体であった。反応温度, 反応時間, 原料組成比などを最適化することにより, 高いシクロヘキサノンオキシム選択率を得ることができた。

Hydrophobic MFI‐Type Zeolites via Alkali‐Cation‐Induced Defect Healing: Implications for Adsorbent and Catalyst Design

Advanced Materials, EarlyView.
Sub‐stoichiometric amounts of Na+ or K+ enhance defect healing during Silicalite‐1 (MFI) and TS‐1 calcination by promoting Si–O–Si annealing and healing framework vacancies. The resulting defect‐free zeolites are more hydrophobic and show improved butanol/water separation and improved activity and selectivity in the epoxidation of 1‐hexene, offering a ...

Cobalt/Photoredox Catalyzed Desymmetrization of Oxo and Azabicycles via Asymmetric Reductive Coupling With Alkynes

Advanced Science, EarlyView.
A one‐step, asymmetric reductive coupling of alkynes and oxa‐ and aza‐bicyclic olefins using a cobalt/photoredox catalytic system through desymmetrization. ABSTRACT Bicyclo[2.2.1]heptane frameworks represent a privileged structural motif prevalent in numerous natural products and bioactive molecules.

Photothermal catalytic synthesis of cyclohexanones from lignin-derived phenolic bio-oils enabling transparent and elastic polyamides

Nature Communications
Cyclohexanones, as critical precursors for polyamide 6, are inherently challenging to synthesize from lignin-derived phenolic bio-oils due to the high dissociation energy of the aryl-OCH3 bond and the competitive risk of C=O bond over-hydrogenation.

Reimagining Lignin Valorization: Synthetic Biology–Enabled Sustainable Aromatic Carbon Biomanufacturing

Advanced Science, EarlyView.
The diagram illustrates a sustainable model of lignin valorization and carbon cycling based on microbial cell factories. Using lignin as the feedstock, synthetic biology technologies, including depolymerization, cell factory construction, pathway gene module integration, and metabolic network regulation, are applied to convert lignin into bulk ...

Programmed Interfacial Phase Separation for Spatiotemporal Fungicide Delivery via Tunable Micro/Nano Architectures

Advanced Science, EarlyView.
ABSTRACT Translating dynamic liquid‐liquid phase separation into robust solid‐state architectures remains a challenge in materials engineering. Here, we report a composition‐driven interfacial assembly strategy that couples supramolecular coacervation with metal‐phenolic coordination to engineer tunable fungicide carriers.

Identification and evaluation of antiviral activity of novel compounds targeting SARS-CoV-2 virus by enzymatic and antiviral assays, and computational analysis

Journal of Enzyme Inhibition and Medicinal Chemistry
The viral genome of the SARS-CoV-2 coronavirus, the aetiologic agent of COVID-19, encodes structural, non-structural, and accessory proteins. Most of these components undergo rapid genetic variations, though to a lesser extent the essential viral ...
