3,5-Disubstituted-indole-7-carboxamides as IKKβ Inhibitors: Optimization of Oral Activity via the C3 Substituent
摘要:
I kappa B kinase beta (IKK beta or IKK2) is a key regulator of nuclear factor kappa B (NF-kappa B) and has received attention as a therapeutic target. Herein we report on the optimization of a series of 3,5-disubstituted-indole-7-carboxamides for oral activity. In doing so, we focused attention on potency, ligand efficiency (LE), and physicochemical properties and have identified compounds 24 and (R)-28 as having robust in vivo activity.
Niobium chloride promoted the nucleophilic addition of allyltrimethylsilane, ethyl acetoacetate, indole and the silyl enol ether derived from acetone to cyclic N-acyliminium ions. The products were obtained in good yields.

metal-catalysed reductive C2-alkoxylation of cyclicimides (phthalimides and succinimides) is presented. Crucial for the success is the use of [Co(BF4)2·6H2O/triphos (L1)] combination and no external additives are required. Using the optimal cobalt-system, the hydrogenation of the aromatic ring of the parent phthalimide is avoided and only one of the carbonyl groups is selectively functionalized. The
提出了第一个通用且有效的非贵金属催化的环状酰亚胺(邻苯二甲酰亚胺和琥珀酰亚胺)的还原性C2-烷氧基化反应。成功的关键是使用[Co(BF 4)2 ·6H 2 O / triphos(L1)]的组合,并且不需要外部添加剂。使用最佳的钴系统,避免了母体邻苯二甲酰亚胺的芳环的氢化,并且仅羰基中的一个被选择性地官能化。所得的产物,N-和芳基环取代的3-烷氧基-2,3-二氢-1H-异吲哚-1-酮和N-取代的3-烷氧基-吡咯烷基-2-酮衍生物是在温和的条件下以良好至优异的分离产率制备的。分子内还原偶联也可以在一步法中进行,从而得到三环化合物。本协议为药物和生物学关注的功能化N杂环化合物的直接合成开辟了新的贱金属工艺开发途径。

is the selective ruthenium‐catalyzed reductive alkoxylation and amination of phthalimides/succinimides. Notably, this novel methodology avoids hydrogenation of the aromatic ring and allows methoxylation of substituted imides with good to excellent selectivity for one of the carbonyl groups. The reported method opens the door to the development of new processes for the selectivesynthesis of various
