with a catalytic amount of TpRuCl(PPh3)2 resulted in the construction of indole scaffolds known as privileged structure motifs. This reaction involved a cascade of 1,2‐rearrangement and cyclization carrying out C−C bond formation via a ruthenium vinylidene intermediate, as revealed by a deuterium‐labeling experiments. Furthermore, the transformation of multi‐functionalized ynamide, derived from a practical
用催化量的TpRuCl(PPh 3)2处理酰胺,导致吲哚支架的构建被称为特权结构基序。如氘标记实验所示,该反应涉及1,2-重排和环化的级联,通过钌-亚乙烯基中间体进行CC键形成。此外,源自实用药物分子的多官能化乙酰胺的转化显示出该反应对官能团的高度耐受性。
