The use of Me3N•SO3 complex was also reported in the sulfation of resveratrol, a naturally occurring polyphenolic that is found in many plants, such as peanuts, grapes, and berries. It was reported that resveratrol has gained more interest due its important biological applications such as antiinflammatory, anti-cancer, and antioxidant activity. The sulfation reaction of resveratrol was carried out using Me3N•SO3 complex in the presence of base (Et3N) at reflux affording the potassium salt of sulfated resveratrol (Scheme 8). Scheme 8.
