Synthesis of indolo[6,7-a]pyrrolo[3,4-c]carbazoles 1, a new class of cyclin D1/CDK4 inhibitors, by oxidation of the corresponding aryl indolylmaleimides 2, will be described. Two approaches to the synthesis of 2 were identified that required new methods for the synthesis of 7-substituted indole acetamides 3 and N-methyl (indol-7-yl)oxoacetates 6. The chemistry developed enabled introduction of functionality
将描述通过相应芳基吲哚基马来酰亚胺2的氧化合成吲哚并[6,7- a ]吡咯并[3,4- c ]咔唑1,一种新型的细胞周期蛋白D1 / CDK4抑制剂。确定了两种合成2的方法,它们需要新的合成7-取代的吲哚乙酰胺3和N-甲基(吲哚-7-基)氧乙酸酯6的新方法。开发出的化学试剂能够在C 12和N 13处引入官能团(-OR,NR 2),从而促进了吲哚并咔唑平台的结构活性关系(SAR)评估。

Reported herein is an iridium‐catalyzed, regioselective silylation of the aromatic CHbonds of benzylamines and the benzylicCHbonds of 2,N‐dialkylanilines. In this process, (hydrido)silyl amines, generated in situ by dehydrogenative coupling of benzylamine or aniline with diethylsilane, undergo selective silylation at the CH bond γ to the amino group. The products of this silylation are suitable for
