Oxylipins are formed in-vivo from polyunsaturated fatty acids (PUFAs). A large structural variety of compounds is grouped under the term oxylipins, which differ from their formation mechanism (involving enzymes or not), as well as their chemical structures (cyclopentanes, tetrahydrofurans, hydroxylated-PUFA etc.). All structures of oxylipins are of great biological interests. Directly correlated to oxidative stress phenomenon, non-enzymatic oxylipins are used as systemic and/or specific biomarkers in various pathologies and more especially, they were found to have their own biological properties. Produced in-vivo as a non-separable mixture of isomers, total synthesis is a keystone to answer biological questions. In this work, we described the total synthesis of three non-enzymatic oxylipins derived from docosahexaenoic acid (DHA) and docosapentanoic acid (DPAn-3) using a unique and convergent synthetic strategy.
