Abstract

En 中文
In this work, we report the cyclization of sulfur-linked tetraynes under 2,2,6,6-tetramethylpiperidine 1-oxyl (TEMPO) radical conditions, leading to the formation of novel pentadehydro-Diels-Alder-type addition products. Through this study, we expand the scope of radical-mediated cyclization reactions of polyyne compounds. The results offer new opportunities for the development of radical-based synthetic methodologies.
