  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.

• Photoredox catalytic alkylarylation of alkynes with arylsulfonylacetate as bifunctional reagent

  Difunctionalization of alkynes represents a powerful and straightforward approach to the synthesis of complex molecules. However, the radical difunctionalization of alkynes mediated by bifunctional reagents remains challenging and underexplored, despite significant progress having been made in alkene difunctionalization. Here, we report a novel arylsulfonylacetate skeleton in which aryl rings are attached

  炔烃的双官能化代表了一种强大而直接的复杂分子合成方法。然而，尽管烯烃双官能化已取得重大进展，但双官能试剂介导的炔烃自由基双官能化仍然具有挑战性且尚未得到充分探索。在这里，我们报道了一种新型芳基磺酰基乙酸酯骨架，其中芳基环通过SO 2连接到乙酸酯上，作为一种强大的双功能试剂，用于在光氧化还原条件下通过乙烯基自由基中间体对炔烃进行烷基芳基化。这种模块化双功能试剂能够同时将多种官能团（包括（杂）芳基环和烷基羧酸酯）结合到炔烃中，从而产生具有合成价值的全碳四取代烯烃衍生物。这种转化的特点是其氧化还原中性、易于获得的起始原料、与不同官能团的相容性及其促进聚合合成的能力。复杂分子的后期功能化以及荧光分子和抗癌药物的制备进一步证明了这种方法的实用性。
• Bu₄NI-Catalyzed Cross-Coupling between Sulfonyl Hydrazides and Diazo Compounds To Construct β-Carbonyl Sulfones Using Molecular Oxygen

  DOI：10.1021/acs.orglett.6b02532

  日期：2016.10.7

  A new cross-coupling reaction between sulfonyl hydrazides and diazo compounds has been established, leading to a variety of beta-carbonyl sulfones in good yields. This methodology was distinguished by simple manipulation, easily available starting materials, and wide substrate scope. A plausible mechanism involving a radical process was proposed based upon the experimental observations and literature.
