  长链吡啶甲酰胺 δ 和 γ 位之间配体控制的正交选择性

  摘要：

  脂肪族 C(sp 3 )–H 键由于其惰性和化学不可区分性，本质上难以激活。这一挑战主要是通过指导小组的方法来克服的；然而，远端脂肪族位置的区域选择性主要依赖于底物，底物偏向是远端 C(sp 3 )–H 激活的先决条件，这是索普-英戈尔德效应的直接结果。将方法扩展到直链脂肪族底物，其中所有可用位置都与功能化兼容，一直是一个长期存在的问题。为此，我们尝试以区域选择性方式开发长链吡啶甲酰胺远端δ和γ位置之间的配体正交选择性。这些烷基胺在吡啶甲酸导向基团的帮助下，只需改变配体即可在其γ和δ位置之间正交官能化，而所有其他反应参数保持不变，这表明配体在控制之间的选择性方面具有巨大的重要性。这种惰性 C(sp 3 )–H 键的上述位置。已经进行了实验和 DFT 研究来概括配体的性质，该配体将成功地促进这些位置之间的正交选择性，富电子吡啶酮配体有利于选择性远端 δ 官能化，而缺电子吡啶酮配体则有利地调整选择性向γ位置。这种从

The discovery and optimization of this novel class of antibacterials by the use of structure-guided design, modeling, and structure-activity relationships are described. Data are presented for enzyme inhibition, antibacterial activity, and in vivo efficacy by oral and intravenous administration in two rodent infection models.
