Abstract

Subtle chemical modifications of an intermediate can have significant impacts, since they usually considered to control the reactivity. In their Research Article, J. Zagranyarski, D. Lungerich, C. Cabanetos, and co-workers report the preparation of aza derivatives of the benzothixanthene imide. The intramolecular radical cyclization can be controlled by means of a simple methylation to either afford the thermodynamically favored six-membered or its kinetically favored five-membered ring regioisomers, exhibiting significant photophysical properties.

封面专题：自由基形成管理：迈向苯并噻吨酰亚胺的氮杂类似物（欧洲化学 1/2024）

对中间体进行微妙的化学修饰会产生重大影响，因为它们通常被认为可以控制反应活性。在他们的研究文章中，J. Zagranyarski、D. Lungerich、C. Cabanetos 及其合作者报告了苯并噻吩亚胺氮杂衍生物的制备过程。分子内自由基环化可以通过简单的甲基化来控制，从而得到热力学上有利的六元环异构体或动力学上有利的五元环异构体，表现出显著的光物理特性。
