以2,4,6-三羟基苯乙酮为原料,碳酸二甲酯(DMC)为甲基化试剂,K2CO3为催化剂,在无相转移催化剂条件下,通过控制反应条件选择性合成了包括花椒油素在内的3种芳甲醚,它们的结构经红外光谱、1H NMR及13C NMR确证。一、二、三取代产物的产率分别为64%、50%、82%。 Using 2,4,6-trihydroxyacetophenone as raw material, dimethyl carbonate (DMC) as methylation reagent and K2CO3 as catalyst, under the condition of no phase transfer catalyst, Three kinds of aryl ethers, including oleyl, their structures were confirmed by IR, 1H NMR and 13C NMR. The yields of primary, secondary and tertiary substituted products were 64%, 50% and 82%, respectively.
