The product obtained by the Pechmanr condensation, followed by the decarboxylation, of p-orsellinic acid with ethyl acetoacetate has been established not to be such 4,5-dimethyl-7-hydroxycoumarin as previously reported, but to be 2,5-dimethyl-7-hydroxychromone.
通过 Pechmanr 缩合,然后对乙酰乙酸乙酯脱羧得到的产物已确定不是先前报道的 4,5-二甲基-7-羟基香豆素,而是 2,5-二甲基- 7-羟基色酮。
