| Summary: | 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<sup>®</sup>, was obtained. The structure of the product was proved by a set of physical methods, including <sup>1</sup>H, <sup>13</sup>C, <sup>19</sup>F NMR, HMBC, HSQC, HRMS and IR spectroscopy. |
