Abstract
Objective To synthesis the high antioxidant activity trans-3,4,5,4'-tetramethoxystilbene.Methods Tetrahydrofuran was used as solvent,3,4,5-trimethoxybenzoic acid aminobenzoic was used as the starting material,after reduction reaction and halogen,Grignard reagent was preparated,with condensation of the star anise aldehyde to preparate target compounds.Results The target compound was determined by MS and 1H-NMR.Conclusion The trans-3,4,5,4'-tetramethoxystilbene can be synthesized by this reaction method.
