Abstract
In the presence of the ionic liquid [bmim]Br/AICl3 as green reaction medium, methyl 12-benzoyldehy-droabietate was synthesized through Friedel-Craftsacylation reactions on the aromatic ring of methyl dehy-droabietate. The optimum synthetic conditions of the tar-get product were found to be as follows: molar ratio of methyl dehydroabietate to [bmim]Br to A1C13 to benzoyl chloride 1:4:8:8, reaction temperature 40℃, reaction time 2 h. The target product was analyzed and characterized by means of IR, MS, NMR and elemental analysis. The results show that this novel method has the advantages of mild condition, short reaction time and environmental benignity.
