三氯化铝催化下的酚类化合物芳环酰化反应,是一个傅-克反应和傅瑞斯重排反应的竟争反应。在反应初期,傅-克反应占据主导地位;在反应后期,傅瑞斯重排反应占据主导地位。另外,通过理化性质,光谱数据和化学相关法,四个新化合物的结构也分别被确定为:2-羟基-3-甲基-4-甲氧基-6-丁酰氧基苯甲酸甲酯(Ⅵ),2-丁酰氧基-3-甲基-4-甲氧基-6-羟基苯甲酸甲酯(Ⅶ),2,4-二甲氧基-3-甲基-6-丁酰氧基苯甲酸甲酯(Ⅷ),4,6-二甲氧基-2-丁酰氧基-3-甲基苯甲酸甲酯(Ⅸ)。 Aluminum trichloride catalyzed aromatic acylation of phenolic compounds is a competitive reaction between Friedel-Crafts reaction and Frieses rearrangement reaction. At the beginning of the reaction, the Friedel-Crafts reaction dominates; in the later stages of the reaction, the rearrangement reaction of Freis dominates. In addition, the structures of the four novel compounds were also identified respectively by physicochemical properties, spectral data and chemical correlation: methyl 2-hydroxy-3-methyl-4-methoxy-6-butyryloxybenzoate (VI), methyl 2-butyryloxy-3-methyl-4-methoxy-6-hydroxybenzoate (VII), 2,4-dimethoxy- Methyl acyloxybenzoate (VIII), methyl 4,6-dimethoxy-2-butyryloxy-3-methylbenzoate (IX).
