Vanillin production from lignin depolymerization by acidic deep eutectic solvent and its possible mechanism

Environmental Progress &Sustainable Energy, EarlyView.
Abstract As one of the most abundant renewable resources and complex aromatic polymers, lignin holds great promise for producing monophenolic compounds. However, its depolymerization into valuable monomers is hindered by intricate side reactions. In this study, alkaline lignin was converted into vanillin using nine choline chloride‐based deep eutectic ...

Enhancing polyphenol synthesis and antioxidant activity in Camellia sinensis using shikimic and salicylic acids

JSFA reports, EarlyView.
Abstract Background Camellia sinensis, widely consumed as tea, is the second most popular beverage globally and is valued for its health benefits. However, environmental stressors pose a significant challenge to the tea industry. This study investigates the potential of shikimic acid (ShA) and its derivative, salicylic acid (SA), as inducers to enhance

2,3‐Dichloro‐5,6‐Dicyano‐1,4‐Benzoquinone (DDQ)‐Mediated CC Bond Formation: Redox Strategies from Stoichiometric to Catalytic Systems

ChemistryOpen, EarlyView.
2,3‐Dichloro‐5,6‐dicyano‐1,4‐benzoquinone serves as a versatile oxidant and redox catalyst for CC bond formation through hydride abstraction or single‐electron transfer. Stoichiometric and catalytic systems enable benzylic, allylic, and aromatic CH activation under mild, metal‐free conditions, providing sustainable routes to complex and bioactive ...
