targeting the γ-aminobutyric acid (GABA) receptor, two series of novel isoxazoline derivatives containing sulfonic and carboxylic esters were designed and synthesized. Their insecticidal activities against Plutella xylostella, Mythimna separata, and Aedes aegypti larvae and their structure–activityrelationship were investigated. The sulfonate-containing isoxazoline derivatives (10k–q) exhibited promising

useful enzymes employed as biocatalysts, especially for the selective oxidation of primary and secondary alcohols, and for the reduction of carbonyl moieties. A new alcohol dehydrogenase (HeADH‐II) has been identified from the genome of the halo‐adapted bacterium Halomonas elongata, which proved stable in the presence of polar organic solvents and salt exposure. Unusual for this class of enzymes, HeADH‐II

Inspired by OxdA that operates biocatalytic aldoximedehydration, we have developed an efficient iron catalyst, Cp*Fe(1,2-Cy2PC6H4O) (1), which rapidly converts various aliphatic and aromatic aldoximes to nitriles with release of H2O at room temperature. The catalysis involves redox activation of the N–O bond by a 1e– transfer from the iron catalyst to the oxime. Such redox-mediated N–O cleavage was
受操作生物催化醛肟脱水的 OxdA 的启发,我们开发了一种高效的铁催化剂 Cp*Fe(1,2-Cy 2 PC 6 H 4 O) ( 1 ),它可以将各种脂肪族和芳香族醛肟快速转化为腈,同时释放H 2 O 在室温下。催化涉及通过 1e 对 N-O 键的氧化还原活化-从铁催化剂转移到肟。这种氧化还原介导的 N-O 裂解通过从酮肟底物的反应中分离出亚氨基亚铁中间体来证明。这种铁催化的无受体脱水方法代表了制备腈的一般方法,它还通过催化 Kemp 消除反应提供水杨腈。
