Abstract The structures assigned to the 5,7-dimethoxy-4-arylcoumarins isolated from Coutarea hexandra have been confirmed by synthesis, via Pechmann condensation of phloroglucinol and an ethyl benzoylacetate derivative, the hydroxy groups of which were protected either by benzylation or by methylenedioxy group formation.
摘要 从 Coutarea hexandra 中分离出的 5,7-二甲氧基-4-芳基香豆素的结构已通过间苯三酚和苯甲酰乙酸乙酯衍生物的 Pechmann 缩合合成得到证实,其羟基被苄基化或亚甲二氧基保护。形成。
