  A B₂(OH)₄-Mediated Synthesis of 2-Substituted Indazolone and Its Application in a DNA-Encoded Library

  摘要：

  Indazolone cores are among the most common structural components in medicinal chemistry and can be found in many biologically active molecules. In this report, a mild and efficient approach to 2-substituted indazolones via B-2(OH)(4)-mediated reductive N-N bond formation is developed. This strategy features mild conditions, no request for a metal catalyst, and a wide scope for both aliphatic and aromatic amines. Meanwhile, this method was further successfully applied on DNA to construct indazolone cores for a DNA-encoded library. This will enable the production of a very attractive indazolone-cored library from simple amines and scaffolds, which will provide considerable diversity.

  A convenient photocatalyst‐free method for the synthesis of redox‐active 1,2‐dihydro‐3H‐indazol‐3‐one derivatives from (2‐nitroaryl)methanol and amines was developed. The reaction proceeded efficiently at room temperature by irradiation of UV light under CO2 atmosphere (1.0 atm, flow) without any photocatalysts or additives. This mild, operationally simple method shows wide functional tolerance. The

  开发了一种简便的无光催化剂方法，可从（2-硝基芳基）甲醇和胺类合成氧化还原活性的1,2-二氢-3 H-吲唑-3-酮衍生物。在室温下，通过在无任何光催化剂或添加剂的情况下，通过在CO 2气氛（1.0 atm，流量）下照射紫外线，使反应有效地进行。这种温和，操作简单的方法显示出广泛的功能公差。由CO 2和胺原位形成的氨基甲酸酯被认为是该反应的关键。已发现通过本方法合成的某些化合物具有较高的抗癌活性，可降低癌细胞系HeLa，MCF-7和U87的活力。
