tricyclic core present in the spiro-pseudoindoxyl natural products has been developed. This involves two intramolecular events: the Au-catalyzed nitroalkyne redox leading to isatogen and its subsequent [3 + 2]-cycloaddition with a suitably positioned olefin. The option to modulate the size of the spiro-annulated ring, which is an important variable in this class of natural products, has been explored. Overall
已经开发出一种简单的用于在螺-伪
吲哚酚天然产物中存在的
三环核的构建的多米诺方法。这涉及两个分子内事件:Au催化的硝基炔氧化还原反应会生成致突变物,以及随后发生的[3 + 2]-环加成反应,并带有适当定位的烯烃。来调节大小的选项螺稠环,这是在这个类
天然产物的一个重要变量,已探索。总体而言,此过程将线性前体成型为具有完整步骤,原子和氧化还原经济性的
