AbstractThe incorporation of sulfonyl fluoride groups into molecules has been proven effective in enhancing their biological activities or introducing new functions. Herein, a transition-metal-free and visible-light-mediated radical tandem cyclization of unsaturated carboxylic acid is reported. This affords a facile access to FSO2-functionalized γ-lactones efficiently, which are critical structural motifs widely present in biologically active molecules.
摘要事实证明,在分子中加入磺酰氟基团可有效增强其生物活性或引入新功能。本文报告了一种无过渡金属和可见光介导的不饱和羧酸自由基串联环化反应。这提供了高效获得 FSO2 功能化 γ 内酯的简便途径,而γ 内酯是广泛存在于生物活性分子中的关键结构基团。
