Description of 3,5-Diacetoxystyrene

3,5-Diacetoxystyrene (also known as 5-Ethenyl-1,3-benzenediol 1,3-diacetate, CAS: 155222-48-3) is a protected styrene derivative with the molecular formula C??H??O?. It features acetyl groups protecting the 3,5-dihydroxy positions on the phenyl ring, enhancing stability and solubility during synthesis. It serves as a crucial intermediate in the production of resveratrol (trans-3,4',5-trihydroxystilbene), a natural polyphenol with antioxidant, anti-inflammatory, and potential health benefits.

Application of 3,5-Diacetoxystyrene

?   Key Intermediate for Resveratrol Synthesis. 3,5-Diacetoxystyrene is widely used as a protected building block in the synthesis of trans-resveratrol (3,4',5-trihydroxystilbene) via palladium-catalyzed Heck coupling with substituted iodobenzenes, followed by deprotection to yield the natural polyphenol with antioxidant properties.

?   Production of Resveratrol Analogs and Derivatives. It serves as a versatile precursor for preparing stilbene derivatives and resveratrol analogs, enabling structural modifications for pharmaceutical research and development of potential anti-inflammatory, anticancer, and neuroprotective compounds.

?   Fine Chemical and Pharmaceutical Intermediate. The acetyl-protected dihydroxy styrene unit provides stability during multi-step organic synthesis, making it valuable in medicinal chemistry for constructing polyphenolic frameworks.

?   Synthesis of Bioactive Stilbenoids. Used in the preparation of natural and synthetic stilbenoids, including combretastatin analogs and other microtubule-targeting agents studied for anticancer activity.

?   Research and Development Applications. Essential reagent in academic and industrial labs for exploring polyphenolic compounds with applications in nutraceuticals, cosmetics, and therapeutic agents.

Storage of 3,5-Diacetoxystyrene

It should be kept in a cool, dry, well-ventilated area at 2–8°C away from heat, sparks, and direct sunlight. Keep containers tightly sealed under an inert atmosphere (nitrogen preferred) to prevent moisture absorption, hydrolysis of acetoxy groups, and potential polymerization. Protect from strong bases, acids, oxidizers, and radical initiators. Handle in a dark place or amber containers to minimize light exposure.
