Abstract : aim to synthesize a new prodrug, resveratrol trinicotinate. methods in presence of lithium and a catalytic amount of naphthalene, the reaction of p - methoxybenzyl trimethylsilyl ether and 3, 5 - dimethoxylbenzaldehyde gave resveratrol after a series of translation. resveratrol trinicotinate was obtained by the reaction of resveratrol and nicotinoyl chloride hydrochloride. results a mutual prodrug resveratrol trinicotinate was designed and synthesized. conclusion a novel method for synthesis of resveratrol and resveratrol trinicotinate has been afforded. the e - isomer is selectivily obtained by dehydration of the compound 2 with khso4
