unactivated C(sp3)−H bonds by cyclic alkylamines mediated by Cu(OAc)2/O2 is reported. This method avoids the use of benzoyloxyamines as the aminating reagent, which are normally prepared from alkylamines in extra steps. A variety of unnatural β2, 2‐amino acid analogues are synthesized by this simple and efficient procedure. This approach offers a solution to the previous unmet challenge of C(sp3)−H/N−H
报道了由Cu(OAc)2 / O 2介导的环状烷基胺对未活化的C(sp 3)-H键进行分子间胺化的第一个例子。该方法避免了使用苯甲酰氧基胺作为胺化试剂,该苯甲酰氧基胺通常是在额外的步骤中由烷基胺制备的。多种非天然β的2,2 -氨基酸类似物是通过这种简单且有效的方法进行合成。这种方法为C(sp 3)-H / N-H活化形成C(sp 3)-N键的先前未解决的挑战提供了解决方案。
Provided herein are antibacterial compounds, wherein the compounds in some embodiments have broad spectrum bioactivity. In various embodiments, the compounds act by inhibition of lipoprotein signal peptidase II (LspA), a key protein in bacteria. Pharmaceutical compositions and methods for treatment using the compounds described herein are also provided.
