tertiary propargylicalcohol precursors. However, none of the enones underwent the desired Nazarov cyclization to a cyclopenta[f]indole. More suitable were 6-hydroxyallylated indolines which gave good yields of cyclopenta[f]indolines after treatment with SnCl4, as soon as sterically demanding beta-cyclocitral adducts were reacted. Most successful were Pt(II) and Au(I)-catalyzedcyclizations of N-TIPS-protected

The present invention relates to substituted pyrimidinyl- and pyridinylpyrrolopyridinone compounds which modulate the activity of protein kinases and are therefore useful in treating diseases caused by dysregulated protein kinase activity, in particular RET family kinases. The present invention also provides methods for preparing these compounds, pharmaceutical compositions comprising these compounds, and methods of treating diseases utilizing pharmaceutical compositions containing these compounds.
本发明涉及替代嘧啶基和吡啶基吡咯吡啶酮化合物,这些化合物调节蛋白激酶的活性,因此在治疗由失调的蛋白激酶活性引起的疾病,特别是 RET 家族激酶方面具有用途。本发明还提供了制备这些化合物的方法,包括这些化合物的药物组合物,以及利用含有这些化合物的药物组合物治疗疾病的方法。

Suzuki–Miyaura cross-coupling, followed by a regioselective reduction employing LiDBB. Starting from 6-iodoindole, the sequence needs nine steps and provided (±)-raputindole A in 6.6% overall yield. The absoluteconfiguration of the natural product (+)-raputindole A was determined by quantum chemical calculation of the ECD spectrum.
据报道,从芸苔植物Raputia simulans中首次合成了双吲哚生物碱RaputindoleA 。关键步骤是Au(I)催化的环化反应,该反应由6烷基化的吲哚啉前体组装成环戊[ f ]吲哚三环。异丁烯基侧链通过Suzuki-Miyaura交叉偶联安装,然后使用LiDBB进行区域选择性还原。从6-碘吲哚开始,该序列需要九个步骤,并以6.6%的总收率提供了(±)-raputindoleA。天然产物(+)-raputindole A的绝对构型是通过ECD光谱的量子化学计算确定的。
