Preparation of Enantioenriched Spirocyclic Scaffolds Transferring Axial Chirality from Borylalkylidenecycloalkanes

open access: yesChemistryEurope, EarlyView.
Enantiomerically enriched borylalkylidenecycloalkanes can transfer axial chirality to spirocyclic compounds with central chirality, without erosion of enantiomeric ratio. The method involves cyclopropanation, borylcyclopropanation, epoxidation, and aziridination reactions, that proceed in astereodivergent manner giving access to spirocycles with ...

Total Synthesis and Analysis of Phenolic Phytoprostanes, Oxidized Derivatives of Lipophenols

open access: yesChemistry – 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

Nature‐Inspired Uv Filters: Synthetic Mycosporine‐Like Amino Acids and Gadusol Analogs for Enhanced Photoprotective and Antioxidant Performance

open access: yesChemPhotoChem, EarlyView.
Photoprotection is a current and relevant topic; therefore, the development of new sunscreens is necessary. To this end, nature is examined for molecules such as mycosporine‐like amino acids and gadusol. Through rational design, this study has successfully synthesized new UV filters and evaluated their photoprotective and antioxidant properties ...
