Two isomeric dimethyl ethers of dicoumarol and derivatives substituted in the methylene group [formulae (XX) and (XXI)] were obtained. This result proves the tautomerism of dicoumarol and suggests for it the coumarin-chromone structure (XXIIa).
获得了二香豆酚和被亚甲基取代的衍生物的两种异构体二甲基醚[式(XX)和(XXI)]。该结果证明了双香豆酚的互变异构现象,并提示了香豆素-色酮结构(XXIIa)。
