  A new series of flavones, thioflavones, and flavanones as selective monoamine oxidase-B inhibitors

  摘要：

  A new series of synthetic flavones, thioflavones, and flavanones has been synthesized and evaluated as potential inhibitors of monoamine oxidase isoforms (MAO-A and -B). The most active series is the flavanone one with higher selective inhibitory activity against MAO-B. Some of these flavanones (mainly the most effective) have been separated and tested as single enantiomers. In order to investigate the MAOs recognition of the most active and selective compounds, a molecular modeling study has been performed using available Protein Data Bank (PDB) structures as receptor models for docking experiments.

  摘要：

  开发了一种有效的无过渡金属的策略，用于通过顺序形成CO键从邻溴代芳基炔酮和苯甲醛肟制备色酮。该环化反应可以很好地耐受各种官能团，并且相应的色酮以中等至极好的收率给出。从机理上讲，苯甲醛肟是一种氢氧化物源，而1，3-二酮衍生物是反应中间体。

  A new method to access flavones in a convergent fashion has been developed, based on the Stork–Danheiser reaction. By this method, 4-methoxy coumarins are allowed to react with organolithium at low temperatures (−78 °C to −40 °C) and then acidic workup gives the desired flavones in 18–86% yields. This method features transition metal-free conditions, readily available starting materials, and simple

  基于 Stork-Danheiser 反应，开发了一种以收敛方式获取黄酮的新方法。通过这种方法，4-甲氧基香豆素可以在低温（-78 °C 至 -40 °C）下与有机锂反应，然后进行酸性处理，得到所需的黄酮，产率为 18-86%。该方法具有无过渡金属条件、起始原料易得、操作简单等特点。当需要快速生成 B 环黄酮衍生物时，它特别有效。

  transition-metal-free strategy was developed for the preparation of chromones from o-bromoaryl ynones and benzaldehyde oxime through sequential C-O bond formation. This cyclization reaction could well tolerate a wide range of functional groups, and the corresponding chromones were given in moderate to excellent yields. Mechanistically, benzaldehyde oxime as a hydroxide source and 1,3-diketone derivatives as reaction
