The behavior of 4-hydroxycoumarin (1), 7-hydroxycoumarin (2), 4-hydroxy-bergapten (3), and 4-hydroxyisopimpinellin (4) toward sulfur reagents, namely, thionyl chloride, phosphorus pentasulfide, thiolacetic acid, and Lawesson's reagent (5), was studied. The nature of products in each case depended upon the type of reactants and reaction conditions. Possible reaction mechanisms were considered, and structural
4-羟基香豆素 (1)、7-羟基香豆素 (2)、4-羟基-香柠檬素 (3) 和 4-羟基异青霉素 (4) 对硫试剂的行为,即亚硫酰氯、五硫化二磷、硫羟乙酸和劳森氏试剂(5),进行了研究。在每种情况下,产物的性质取决于反应物的类型和反应条件。考虑了可能的反应机制,新产品的结构解析基于兼容的元素和光谱证据。
