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。

Generation of reactive α-oxogold carbene intermediates via gold-catalyzed oxidation of alkynes has become an increasing versatile strategy of replacing hazardous diazo carbonyl compounds with benign and readily available alkynes in the development of efficient synthetic methods. However, one of the hallmarks of metal carbene/carbenoid chemistry, i.e., insertion into an unactivated C(sp(3))-H bond
This invention relates to novel compounds useful in the treatment of diseases associated with TRPV4 channel receptor. More specifically, this invention relates to certain acyclic diamines, which are agonists of TRPV4 channel receptors.
