In this report, we describe a halo-Prins/aryl halo-Nazarov cyclization strategy that employs readily available starting materials, inexpensive reagents, and convenient reaction procedures to generate functionalized haloindenes and indanones. The scope and limitations of the method are outlined, demonstrating that aromatic systems readily react under mild, catalytic conditions when this strategy is
在本报告中,我们描述了一种卤代-Prins/芳基卤代-纳扎罗夫环化策略,该策略使用容易获得的起始材料、廉价的试剂和方便的反应程序来生成功能化的卤代
茚和
茚满酮。概述了该方法的范围和局限性,表明实施该策略时,
芳烃系统很容易在温和的催化条件下反应。此外,我们提供了实验和计算数据,支持这样的观点,即 3-卤代
戊二烯基阳离子中间体的环化比类似的 3-氧
戊二烯基阳离子系统的环化在动力学上更容易获得,并且在热力学上更有利。
