A yellow pigment isolated from the title solution is proposed to be a tautomeric mixture of 3-hydroxy-5-methoxy-2,6-dimethyl-6-(2-methylbutyryloxy)-2,4-cyclohexadien-1-one and 3-hydroxy-5-methoxy-2,4-dimethyl-4-(2-methylbutyryloxy)-2,5-cyclohexadien-1-one on the basis of methylation experiment which give two products corresponding to both forms.
从标题溶液中分离出的黄色
颜料被认为是 3-羟基-5-甲氧基-2,6-二甲基-6-(2-甲基丁酰氧基)-2,4-环
己二烯-1-酮和 3- 的互变异构混合物。羟基-5-甲氧基-2,4-二甲基-4-(2-甲基丁酰氧基)-2,5-环
己二烯-1-酮基于甲基化实验,得到对应于两种形式的两种产物。
