(3a,8b)-5-Acetyl-3a-fluoro-6,8-dihydroxy-7,8b-dimethyl-3,3a-dihydrofuro[3,2-b]benzofuran-2(8bH)-one
Usnetic acid is a dibenzofuran-2-ylacetic acid that can be obtained by alkaline degradation of a secondary lichen metabolite—usnic acid. In the present paper, the product of the reaction of usnetic acid with a mild fluorinating agent, Selectfluor®, was obtained. The structure of the product was proved by a set of physical methods, including 1H, 13C, 19F NMR, HMBC, HSQC, HRMS and IR spectroscopy.
