4-chloromethyl-6-hydroxycoumarins have been obtained by the condensation of hydroquinone derivatives with 4-chloroacetoacetic ester, and have been used for the synthesis of 4-(2-benzofuryl)-6-hydroxycoumarins. Alkylation and acylation of the phenolic hydroxyl of the synthesized 4-(2-benzo-furyl)coumarins have been investigated.
通过氢醌衍生物与4-氯乙酰乙酸酯的缩合反应获得了新的4-氯甲基-6-羟基香豆素,并将其用于合成4-(2-苯并呋喃基)-6-羟基香豆素。已经研究了合成的4-(2-苯并呋喃基)香豆素的酚羟基的烷基化和酰化。
