• Catalytic Enantioselective [2,3]-Rearrangements of Allylic Ammonium Ylides: A Mechanistic and Computational Study

  A mechanistic study of the isothiourea-catalyzed enantioselective [2,3]-rearrangement of allylic ammonium ylides is described. Reaction kinetic analyses using 19F NMR and density functional theory computations have elucidated a reaction profile and allowed identification of the catalyst resting state and turnover-rate limiting step. A catalytically relevant catalyst–substrate adduct has been observed

  描述了异硫脲催化的烯丙基铵叶立德的对映选择性 [2,3] 重排的机理研究。使用 19F NMR 和密度泛函理论计算的反应动力学分析阐明了反应曲线并允许识别催化剂静止状态和周转率限制步骤。已经观察到催化相关的催化剂 - 底物加合物，其组成通过 13C 和 15N 同位素标记明确阐明。同位素夹带表明观察到的催化剂-底物加合物是催化生产循环中真正的中间体。已经检查了 HOBt 作为添加剂对反应、催化剂静止状态和周转率限制步骤的影响。交叉实验已经探讨了催化循环中每个建议步骤的可逆性。计算也被用来阐明立体控制的起源，1,5-S···O 相互作用和催化剂立体定向基团提供了过渡结构刚性和对映选择性，同时偏爱阳离子-π 相互作用而不是 C-H···π负责非对映选择性。
• Enantioselective Sulfonium–Claisen Rearrangement with Cinnamyl Thioethers

  日期：2023.6.2

  Sulfonium–Claisen rearrangement leveraged by the gold-catalyzed formation of allyl sulfonium intermediates has enabled an exceptional level of regio- and enantiocontrol for the synthesis of skipped 1,4-dienes. However, the application of cinnamyl thioether derivatives to the sulfonium–Claisen rearrangement has been unsuccessful so far due to the extensive dissociation of the cinnamyl cation. By fine-tuning

• Structure Mechanism Insights and the Role of Nitric Oxide Donation Guide the Development of Oxadiazole-2-Oxides as Therapeutic Agents against Schistosomiasis

  Schistosomiasis is a chronic parasitic disease affecting hundreds of millions of individuals worldwide. Current treatment depends on a single agent, praziquantel, raising concerns of emergence of resistant parasites. Here, we continue our explorations of an oxadiazole-2-oxide class of compounds we recently identified as inhibitors of thioredoxin glutathione reductase (TGR), a selenocysteine-containing flavoenzyme required by the parasite to maintain proper cellular redox balance. Through systematic evaluation of the core molecular structure of this chemotype, we define the essential pharmacophore, establish a link between the nitric oxide donation and TGR inhibition, determine the selectivity for this chemotype versus related reductase enzymes, and present evidence that these agents can be modified to possess appropriate drug metabolism and pharmacokinetic properties. The mechanistic link between exogenous NO donation and parasite injury is expanded and better defined. The results of these studies verify the utility of oxadiazole-2-oxides as novel inhibitors of TGR and as efficacious antischistosomal agents.
• Synthesis of oxadiazole-2-oxide analogues as potential antischistosomal agents

  日期：2009.4

  The synthesis of several 1,2,5-oxadiazole-2-oxide (Furoxan) analogues is described herein. These compounds were prepared in an effort to probe the SAR around the phenyl substituent and oxadiazole core for our studies toward thioredoxin-glutathione reductase (TGR) inhibition and antischistosomal activity.
