有机腈构成有机合成中的关键前体和中心中间体。另外,腈是在许多医学和生物学上重要的化合物中发现的通用基序。通常,这些腈是使用有毒氰化物通过传统的氰化步骤合成的。本文中,我们报道了使用可重复使用的基于“纳米锈”(纳米级Fe 2 O 3)的分子氧催化剂,伯胺选择性和环境无害的氧化转化,用于合成结构多样的芳香族,脂肪族和杂环腈。

The selective oxidation of amines for the benign synthesis of nitriles under mild conditions is described. Key to success for this transformation is the application of reusable cobalt oxide-based nanocatalysts. The resulting nitriles constitute key precursors and central intermediates in organic synthesis.
Disclosed herein are isoxazole derivaties and uses thereof. Serving as agonists of Wnt, the isoxazole derivatives activate Wnt/β-catenin signaling and thus can be used in the treatment and prevention of diseases related to the signal transduction. Also, pharmaceutically acceptable salts of the isoxazole derivatives are disclosed.

Adamantyl ureas are good soluble epoxide hydrolase (sEH) inhibitors; however they have limited solubility and rapid metabolism, thus limiting their usefulness in some therapeutic indications. Herein, we test the hypothesis that nodal substitution on the adamantane will help solubilize and stabilize the compounds. A series of compounds containing adamantane derivatives and isoxazole functional groups were developed. Overall, the presence of methyl on the nodal positions of adamantane yields higher water solubility than previously reported urea-based sEH inhibitors while maintaining high inhibition potency. However, it did not improve microsomal stability. (C) 2015 Elsevier Ltd. All rights reserved.

A series of 1,3-disubstituted and 1,3,3-trisubstituted isoxazolyl- and adamantyl-functionalized ureas was synthesized. The resulting compounds are potent inhibitors of soluble epoxide hydrolase. The compounds were obtained in high yields under mild conditions. Water solubility of the synthesized ureas was found to exceed significantly that of known analogs.
