  摘要：

  报道了一种从磺酰胺中简单实用地合成磺酰氟的方法。该方法利用 Pyry-BF4 和 MgCl2 反应形成磺酰氯，随后在 KF 的存在下原位转化为更稳健和稳定的磺酰氟。该协议的温和条件和高化学选择性使磺酰氟从密集功能化分子的后期形成成为可能。由于其在化学生物学领域的成功活动，在其结构中带有磺酰氟的复杂有机分子的合成获得了巨大的动力。由于其独特的化学性质，几种磺酰氟已被用作化学生物学中的弹头，以靶向氨基酸残基并充当基于活性的探针（图 1）。图1。功能化芳基磺酰氟作为活性探针的例子。文献中提供了多种磺酰氟的合成方法，从无数不同的起始材料开始。早期的合成可以从磺酰肼、硫代磺酸盐、磺酰氯、磺酸、磺酸盐等中找到（图 2A）。然而，这些传统方法中的大多数在官能团兼容性方面受到限制，并且需要合成步骤才能获得起始材料。在最近的方法中，Willis、Bagley 和 Ball 独立解决了这些问题，并报告了使用简

  The first metal-free procedure for the synthesis of arylsulfonyl fluorides is reported. Under organo-photoredox conditions, aryl diazonium salts react with a readily available SO2 source (DABSO) to afford the desired product through simple nucleophilic fluorination. The reaction tolerates the presence of both electron-rich and -poor aryls and demonstrated a broad functional group tolerance. To shed

  We report here a SuFEx-enabled, agnostic approach for the discovery and optimization of covalent inhibitors of human neutrophil elastase (hNE). Evaluation of our ever-growing collection of SuFExable compounds toward various biological assays unexpectedly revealed a selective and covalent hNE inhibitor: benzene-1,2-disulfonyl fluoride. Synthetic derivatization of the initial hit led to a more potent
