  摘要：

  利用 N-链烯氧基吲哚中间体的反应性，开发了一种简洁的呋喃 [2,3-b] 吲哚啉合成路线。这些化合物自发地经历 [3,3]-σ 重排，然后环化形成作为单一非对映异构体的半缩氨酸。锡促进的 N-羟基吲哚形成，然后与活化炔烃的共轭加成提供了对各种 N-烯氧基吲哚及其相应呋喃 [2,3-b] 吲哚啉的简单和模块化的访问。微型高通量实验用于促进对这种转化的范围和耐受性的研究，并且还评估了对 N-羟基吲哚与卤代芳烃的亲核芳香取代和重排的相关研究。

  一种甲基磺草酮中间体的制备方法

  摘要：

  本发明涉及一种甲基磺草酮中间体的制备方法，对甲磺酰基溴苯作为起始原料，首先和硝酸发生硝化反应，将反应后体系用乙酸乙酯与饱和碳酸氢钠水溶液进行萃取处理，出去有机相得到产物；然后以DMF作为溶剂与氰化亚铜在高温下发生氰化反应，除去体系中溶剂，通过柱层析分离产物；将产物进行水解酸化得到最终产物甲基磺草酮中间体2‑硝基‑4‑（甲基磺酰基）苯甲酸。将该方法相比于传统的合成方法，减少了强氧化剂的使用，反应条件较为温和，增加了操作安全性，同时各步反应处理容易，有利于反应的进行，具有较高的产率。

  We describe a synergistic catalysis strategy for the asymmetric direct addition of simple aldehydes to 4-vinylpyridines. By means of independent activation of weakly electrophilic 4-vinylpyridines by the Brønsted acid CF3SO3H (TfOH) and aldehydes by chiral diphenylprolinol tert-butyldimethylsilyl (TBDMS) ether-catalyzed formation of nucleophilic enamines in a cooperative manner, the previously unattainable
