Abstract
Arachidonic acid (AA, C20 :4, n-6) and docosahexaenoïc acid (DHA, C22 :6, n-3) are phospholipidic membranes polyinsaturated fatty acids. During and oxidative stress, these are metabolized into tetrahydrofuran-containing compounds, known as isofurans (IsoFs) for AA and neurofurans (NeuroFs) for DHA. We were interested in the total synthesis of these compounds in the aim of getting access to novel biomarkers of the oxidative stress. Towards the same goal, we envisaged the total synthesis of potential analog structures coming from adrenic acid (AdA, C22 :4, n-6), that we named dihomo-isofurans (dihomo-IsoFs).
