  在水介质中用亚硫酸钠对苯酚和杂芳族化合物进行还原脱卤和脱卤磺化

  摘要：

  质子互变异构被用作在水介质中使用亚硫酸钠作为唯一试剂的（杂）芳基溴化物和碘化物的还原性脱卤化或（杂）芳基氯和氟化物的脱卤化磺化的工具。该方案不需要金属或相转移催化剂，避免使用有机溶剂作为反应介质。此方法特别适用于容易互变异构的底物（例如2-或4-卤代氨基酚和4-卤代间苯二酚），在温和的反应条件下（≤60°C）会进行脱卤或磺化。由于亚硫酸钠是一种廉价，安全且对环境无害的试剂，因此该方法至少具有三个潜在应用：（i）使用亚硫酸钠作为还原剂对卤素作为保护基进行脱保护；（ii）在温和的反应条件下磺化芳族卤化物，避免使用危险和腐蚀性的试剂/溶剂；（iii）将有毒的卤代芳族化合物转化为危害较小的化合物。

• Synthesis and Structure–Activity Relationships of Tambjamines and B-Ring Functionalized Prodiginines as Potent Antimalarials

  日期：2015.9.24

  Synthesis and antimalarial activity of 94 novel bipyrrole tambjamines (TAs) and a library of B-ring functionalized tripyrrole prodiginines (PGs) against a panel of Plasmodium falciparum strains are described. The activity and structure–activity relationships demonstrate that the ring-C of PGs can be replaced by an alkylamine, providing for TAs with retained/enhanced potency. Furthermore, ring-B of

  描述了94种新型联吡咯他布明胺（TAs）的合成和抗疟活性以及针对一系列恶性疟原虫菌株的B环功能化三联吡咯酮（PGs）库。活性和结构-活性之间的关系表明，PGs的C环可以被烷基胺取代，从而为TAs提供保留/增强的效力。此外，PG / TA的B环可以在4位（取代OMe）或3位和4位上被短烷基取代而不影响效能。已评估了八个代表性TA和两个PG对耐多药疟原虫的抗疟活性口服给药的小鼠剂量范围为5-100 mg / kg×4天。KAR425 TA的功效比以前任何PG所观察到的都要大，在25天和50 mg / kg×4天的剂量下，直到28天之前，对感染疟疾的小鼠提供100％的保护，并且在该模型中也可以单次口服治疗（80毫克/公斤）。这项研究提出了tambjamines中抗疟活性的第一个解释。
