Abstract

The 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.
