  A new procedure for the conversion of thiols into reactive sulfenylating agents

  摘要：

  Thiols may be converted in high yield into unsymmetrical 2-pyridyl disulfides 3. Treatment of these with alkylating agents (e.g., alkyl fluorosulfonates or oxonium salts) affords the corresponding N-alkylpyridyl disulfides 4, which are potent sulfenylating agents (Scheme II) and react smoothly with a variety of sulfur nucleophiles (e.g., thiols, thiones, thioamides, dithiocarbamates, thiocyanate, etc.) to afford disulfides, with amines to afford sulfenamides, and with beta-diketones to afford sulfides. This new method is particularly well-suited to the preparation of unsymmetrical disulfides and sulfenamides from complex and otherwise reactive thiols.

  thiols with (diacetoxyiodo)benzene (DIB) has been explored in the preparation of symmetrical disulfides and sulfenamides. Disulfides can be produced in excellent yields (75–95 %) upon treatment of thiols with DIB. The reaction was complete in less than five minutes at room temperature. Aliphatic, aromatic, and heteroaromatic thiols are compatible with this transformation. Moreover, heteroaromatic disulfides

  在对称二硫化物和次磺酰胺的制备中，已经探索了用（二乙酰氧基碘）苯 (DIB) 活化硫醇的硫原子。用 DIB 处理硫醇后，二硫化物可以以极好的收率 (75–95%) 产生。在室温下反应在不到五分钟内完成。脂肪族、芳香族和杂芳香族硫醇与这种转化相容。此外，从杂芳族硫醇获得的杂芳族二硫化物在碱存在下进一步与亲核胺反应，以一锅法以相当到良好的产率（43-90%）提供相应的次磺酰胺。该方法成功地扩展到吲哚作为一种代表性的富电子芳香化合物，从而可以在一锅中成功构建 S-C 键。

  An iodine-mediated sulfenamides synthesis was reported. By using iodine as oxidant, various heterocyclic thiols and amines (mainly secondary amines) could smoothly proceed the CDC reaction, affording the target N−S formation products with good yields. The protocol features metal-free, easy performance, and short reaction time.

  Heteroaryl 2‐sulfonamides are an important structural moiety in drug discovery. However, reports of the efficient synthesis of these scaffolds are rare. Herein we disclose new reaction conditions to synthesize heteroaryl 2‐sulfonamides from disulfanes and amines through an SN2‐oxidation cascade. The approach is compatible with a wide variety of heteroaryl and amine substrates and can be conducted on a gram scale. A potential Werner Syndrome Protein (WRN) small molecule inhibitor H3B‐968 was also synthesized by this method.
