accomplished through an organo-photocatalyzed decarboxylative intramolecular cyclization using readily available 1,2-diaza-1,3-dienes and α-ketoacids. This method allows for the systematic synthesis of substituted pyrazole derivatives. Notably, this approach is characterized by its metal-free and oxidant-free nature, offering distinct advantages such as short reaction times and exceptionally mild reaction
四取代吡唑的合成具有重要的合成价值,并且是通过使用容易获得的 1,2-二氮杂-1,3-二烯和 α-酮酸进行有机光催化脱羧分子内环化来完成的。该方法允许系统合成取代的吡唑衍生物。值得注意的是,该方法的特点是不含金属和氧化剂,具有反应时间短和反应条件异常温和等独特优势。所开发的方法能够有效构建四取代吡唑,扩大可用于探索的化学空间并在各个科学领域开辟潜在应用。
