据报道,通过C(sp 3)-H键活化,用强力的二恶唑酮酰胺化剂对硫酰胺进行温和,无氧化剂和选择性Cp * Co III催化的酰胺化酰胺化反应,以生成所需的酰胺化产物。该方法是有效的,并且可以在Cp * Co III催化条件下,将各种官能化的硫酰胺与芳基,杂芳基和烷基取代的二恶唑酮进行CH酰胺化反应。观察到的对原代C的区域选择性(sp 3)-H活化得到计算研究的支持,并且建议通过外部羧酸盐辅助的协同金属化/去质子化机理进行环金属化。所报道的方法是一个罕见的使用指导基团而不是常用吡啶和喹诺酮类用于Cp * Co III催化的C(sp 3)-H功能化的方法,也是第一个利用硫代酰胺的方法。

The first rhodium(I)‐catalyzedenantioselective intermolecular C–Hactivation of various saturated aza‐heterocycles including tetrahydroquinolines, piperidines, piperazines, azetidines, pyrrolidines, and azepanes is presented. The combination of a rhodium(I) precatalyst and a chiral monodentate phosphonite ligand is shown to be a powerful catalytic system to access a variety of important enantio‐enriched
Compounds of formula (I) are disclosed. Compounds according to the invention bind to and are agonists, antagonists or inverse agonists of the CB2 receptor, and are useful for treating inflammation. Those compounds which are agonists are additionally useful for treating pain.
