  摘要：

  The (S)-2-nitro-6-(4-(trifluoromethoxy)benzyloxy)-6,7-dihydro-5H-imidazo[2,1-b][1,3]oxazine named PA-824 (1) has demonstrated antitubercular activity in vitro and in animal models and is currently in clinical trials. We synthesized derivatives at three positions of the 4-(trifluoromethoxy)benzylamino tail, and these were tested for whole-cell activity against both replicating and nonreplicating Mycobacterium tuberculosis (Mtb). In addition, we determined their kinetic parameters as substrates of the deazaflavin-dependent nitroreductase (Ddn) from Mtb that reductively activates these pro-drugs. These studies yielded multiple compounds with 40 nM aerobic whole cell activity and 1.6 mu M anaerobic whole cell activity: 10-fold improvements over both characteristics from the parent molecule. Some of these compounds exhibited enhanced solubility with acceptable stability to microsomal and in vivo metabolism. Analysis of the conformational preferences of these analogues using quantum chemistry suggests a preference for a pseudoequatorial orientation of the linker and lipophilic tail.

  dihydroxylation of alkenes is one of the most powerful synthetic tools for delivering two hydroxyl groups at vicinal positions. The direct formation of 1,3-diols remains a formidable challenge, yet dihydroxyl groups are broadly present in bioactive compounds, and are currently only available synthetically via multiple steps. The oxidative ring-opening of arylcyclopropanes has been demonstrated to access various

  传统的烯烃二羟基化是在邻位提供两个羟基的最强大的合成工具之一。直接形成 1,3-二醇仍然是一个艰巨的挑战，但二羟基广泛存在于生物活性化合物中，目前只能通过多个步骤合成。芳基环丙烷的氧化开环已被证明可以得到各种 1,3-双官能化化学物质，但由于 1,3-二醇本身很容易被进一步氧化，所以尚未直接合成 1,3-二醇。在此，我们报告了一种简便有效的 1,3-二醇策略，涉及用 H 2控制芳基环丙烷的电化学 C-C 键断裂O作为最终的绿色羟基源。此外，该方案以其高原子经济性、广泛的底物范围和优异的官能团耐受性而脱颖而出，因此适合复杂天然产物和药物衍生物的合成。
