  Fingerprint lipolytic enzymes with chromogenic p-nitrophenyl esters of structurally diverse carboxylic acids

  摘要：

  A series of structurally diverse chromogenic esters, including a new compound (4-nitrophenyl 2-methylpentanoate), has been synthesized, constituting an array of 17 substrates which could be applied to rapidly fingerprint the activity of lipases or esterases to reveal their substrates specificity and functional characteristics. Combined with genetic technology such as "data mining" and directed evolution, such fingerprints might be a promising platform for discovery of potentially useful enzymes in industrial application. The fingerprint of commercially available Lipase-B from Candida antarctica as a model enzyme was first measured to confirm the reliability of this method. Then three new enzymes mined from genomic libraries were successfully fingerprinted, revealing the functional characteristics of those enzymes. Among them, the enzyme SrfAD was founded with specific substrate preference towards cycloalkyl carboxylic esters and aromatic esters, making it more promising in synthetic utilities than other tested enzymes.

  可见光催化的亚硝基形成形成的[1 + 2 + 2]环加成反应

  摘要：

  硝基是有机合成中的关键中间体。本文中，我们报道了由硝基芳烃和芳基胺进行的光催化还原亚甲基中间体中间体。高反应性的亚甲基硝基酮被烯烃原位捕获，得到各种异恶唑烷。此三组分反应的特征是使用N，N-二甲基苯胺或N-芳基甘氨酸作为C1结构单元，可从简单的起始原料进行一锅形式的正式[1 + 2 + 2]环加成。在温和的条件下，可以以中等至良好的收率获得各种有用的异恶唑烷。机理研究支持通过选择性的N-CH 3键裂解和亚甲基转移形成亚甲基硝酮。
