HKI 0231B(1b)的总合成以12个线性步骤完成,总产率为15.6%。不寻常的阴离子环化提供了对中间体61和嵌入的苯并[ cd ]吲哚-3-(1H)-一环系统3的访问。在酮存在下进行定向邻位锂化,然后进行甲酰化,最后进行酸催化的甲醇分解,完成了合成。还报道了针对存在于HKI 0231A(1a)中的内酰胺缩醛官能团的构建和反应性的研究。
The totalsynthesis of HKI 0231B (1b) was completed in 12 linear steps and 15.6% overall yield. An unusual anionic cyclization provided access to intermediate 61 and the embedded benz[cd]indol-3-(1H)-one ring system 3. Directed ortho-lithiation in the presence of a ketone followed by formylation and finally acid-catalyzed methanolysis complete the synthesis. Studies directedtoward the construction
