two‐step: Chroman‐3‐ones are important intermediates for organic synthesis and medicinal chemistry. However, their syntheses require multiple steps and are not efficient. By using gold‐catalyzed alkyne oxidation, this versatile heterocycle can be prepared in only two steps from readily available phenols and with mostly high efficiencies (see scheme).
两步法:Chroman-3-ones 是有机合成和药物化学的重要中间体。然而,它们的合成需要多个步骤并且效率不高。通过使用金催化的炔烃氧化,这种多功能杂环可以从容易获得的酚类中仅通过两步来制备,而且效率很高(参见方案)。
