A direct and structurally divergent synthesis of indole alkaloids from very simple 2‐vinylanilines, alkynes and TBN via a novel substrate fragmentation/cycloaddition strategy has been developed, which provides an efficient noble‐metal‐free approach to access a library of highly valuable indole derivatives of tryptamines and tryptamine‐related oximes, lactams, and lactones, as well as β‐carbolines,
已开发出一种新颖的底物裂解/环加成策略,可从非常简单的2-乙烯基苯胺,炔烃和TBN直接合成并在结构上多样化的吲哚生物碱,这提供了一种无贵金属的有效方法,可访问高度有价值的吲哚衍生物库包括色胺和色胺相关的肟,内酰胺和内酯,以及β-咔啉,螺二吲哚和六氢吡咯并[2,3- b ]吲哚。
