1,2,6‐Thiadiazin‐4‐ones: Robust Photocatalysts for the Green Aerobic Oxidation of Sulfides to Sulfoxides

European Journal of Organic Chemistry, EarlyView.
A new photocatalyst for the aerobic photochemical oxidation of sulfides to sulfoxides is described under really low catalyst loading (0.01 mol%) and methanol as the green solvent. The chemoselective oxidation of sulfides to sulfoxides is accomplished using a new family of photocatalysts, namely 1,2,6‐thiadiazin‐4‐ones. Utilizing a low catalyst loading (

Effect of Fruit Maturation Stage on the Chemical Composition and Antioxidant and Cytotoxic Activities of Piper nigrum Essential Oil

Flavour and Fragrance Journal, EarlyView.
The essential oils of Piper nigrum show marked chemical and biological variation across fruit maturation stages. Ripe fruits yield oils with the strongest antioxidant and cytotoxic activities, demonstrating that maturation directly modulates volatile composition and enhances the bioactive potential of this aromatic species.
