标题:通过非贝克曼机制途径从酮肟电化学形成 α-酮酰胺
摘要:α-酮酰胺由于与多种天然产物和药物分子结合,在合成化学中具有很高的价值.在这里,我们提出了一种用于构建 α-酮酰胺的创新电化学方法,在恒定电流下,在用户友好的未分割电池设置中采用温和且环保的策略.与以前具有挑战性的方法相比,优异的官能团耐受性,反应仪器和起始材料的方便可及性以及易于扩展性共同增强了该协议的重要性.此外,通过研究反应物的循环伏安图,可以深入了解该反应的机理.

标题 :Method of preparing a polymeric coating composition
摘要:A method of preparing a storage-stable one-part reactive liquid thermal curing polymeric coating composition from an isocyanate-functional polymeric compound which has a substantial portion of its isocyanate groups masked with an isocvanate masking agent, and a crosslinking agent which is substantially insoluble in aprotic solvents. These liquid compositions are homogeneous even when free of solvents. Preferably the crosslinking agent is a crystalline polyol. The method involves the synthesis of a solubilizing oligomer which is formed by the partial reaction of the crosslinking agent and the unmasked isocyanate-functional polymeric compound. The thermal curing of these compositions results in polymeric coatings which possess superior physical properties. These cured coatings are particularly useful in the manufacture of retroreflective sheeting.

摘要:The present invention relates to a process for the production of benzimidazole derivatives comprising providing an amino acetamido benzene derivative; and condensing and cyclising the aminoacetamido benzene derivative in the presence of a base and in the presence of a cyclising agent under conditions effective to form the benzimidazole derivative. The acetamido benzene derivative has the formula (I) wherein R is OMe or OCHF2. The resulting substituted benzimidazoles are key intermediates in the synthesis of H<+>/K<+>-ATPase irreversible inhibitors, most particularly Omeprazole.
