  镁介导的磺酰氯与脂肪族卤化物的偶联反应可有效合成脂肪族砜†

  摘要：

  在超声处理下，磺酰氯与镁还原为无水亚磺酸盐。在催化的碘化钠存在下，在超声处理下，用烷基氯将这些亚磺酸盐烷基化为砜。通过这一一锅两步程序，可以有效地制备各种脂肪族砜。

  Ruthenium(II) complexes catalyze the insertion of sulfur dioxide into (het)aryl and alkenyl boronic acids. The transmetalation–sulfination process proceeds with DABSO in the presence of 5 mol % RuCl2(PPh3)3 in methanol at 100 °C. The intermediate sulfinate salt can be quenched with various electrophiles such as alkyl halides, epoxides, Michael acceptors, and λ3-iodanes in moderate to good yields. The

  钌（II）配合物催化二氧化硫插入（杂）芳基和烯基硼酸中。在5 °C的RuCl 2（PPh 3）3在100°C的甲醇中，DABSO进行了金属转移-硫化过程。中间亚磺酸盐可以与各种亲电猝灭如烷基卤，环氧化物，迈克尔受体，和λ 3 -iodanes在中度至良好的产率。所报告的砜合成可根据亲电试剂的反应性，以直接一锅法或一锅两步法进行。

  The present disclosure encompasses compounds and compositions that are useful as specific AI-2 antagonists for the control of bacterial quorum sensing. Although the AI-2 antagonists according to the present disclosure may not have bactericidal effect, their ability to attenuate virulence, drug resistance, and/or biofilm formation have therapeutic benefits. In addition, the AI-2 antagonists of the present disclosure can also be used as tools to probe bacterial AI-2 functions. The present disclosure also encompasses methods for inhibiting or attenuating microbial virulence, biofilm formation, and drug resistance. The methods are suitable for preventing bacteria from accruing and forming extensive biofilms that may be a health or hygiene hazard or a physical issue, such as in the blockage of water or fuel lines.
