Total Synthesis and Analysis of Phenolic Phytoprostanes, Oxidized Derivatives of Lipophenols
Chemistry – A European Journal, EarlyView.The total synthesis of four hydroxytyrosol‐phytoprostanes (PhytoPs‐HT) was achieved in 20 steps, enabling their first identification as HT‐α‐linolenate oxidation products. This work revealed new oxidized derivatives of lipophenols via UHPLC‐MS/MS analysis, offering a strategy to trace HT‐derived compounds in complex matrices, aiding food and biomedical

Chemistry – A European Journal, EarlyView.A detailed account on the synthesis of a bicyclo[3.2.1]octane scaffold, common to the kaurane, grayanane, and gibberellane diterpenoid families, is reported. Our original strategy relying on a 1,4‐sila‐Prins cyclization proved unsuccessful. Learning from that, we designed an alternative strategy relying on ring‐closing metathesis (RCM), which ...
