참여 물질

반응 단계

50 mg (0.14 mmol) of (E)-3,4′,5-triacetoxystilbene was dissolved in 3 ml methanol and degassed with argon. 8 mg (0.14 mmol) of potassium hydroxide in 0.5 ml methanol were added dropwise under a slight argon stream and the mixture was heated for 30 minutes to 65° C. The obtained solution was neutralized with 1 N hydrochloric acid, poured into 10 ml of ethyl acetate and extracted 3× against 5 ml of brine. The organic phase was dried over MgSO4 and the solvent removed in vacuo giving 30 mg of resveratrol (0.13 mmol, 92%).
