A variety of cyclopropyl aryl ketones undergo uncatalyzed cascade ring-opening/recyclization reactions to generate indenones and fluorenones. In addition, a new strategy to access 3-hydroxyindanones possessing two contiguous stereogenic centers, one of them being an all-carbon quaternary center, was also established. During the course of the investigation, pronounced solvent, temperature, and substituent
各种环丙基芳基酮经过未催化的级联开环/再循环反应生成茚满和芴酮。此外,还建立了一种新的访问3-羟基茚满酮的新策略,该3-羟基茚满酮具有两个连续的立体生成中心,其中一个是全碳四元中心。在研究过程中,发现了明显的溶剂,温度和取代基对产物分布的影响。
