Abstract
Lipophilic saturated and unsaturated L-ascorbyl 5,6-O-diesters from fatty acids are prepared and fully characterized through NMR and MS spectra. Derivatives with different sulfurated moieties are obtained as well through thio-Michael addition of thiols on ascorbyl acrylates. The new amphiphilic structures exhibit very high antioxidant activity using the DPPH assay.
