Bisosthenon (1), a new dimeric coumarin, was isolated from the roots of some Citrus plants (Rutaceae), and the structure was elucidated to be 1, correspoding to a head-to-head dimer of osthenon (4), which was previously obtained from Citrus plants. The photodimerization of 4 gave 1 as well as two other dimeric products, 2 and 3.
从一些柑橘类植物(芸香科)的根中分离出了一种新的二聚
香豆素--双
酚(1),并阐明了其结构为 1,与之前从柑橘类植物中获得的奥司他农(4)的头对头二聚体相对应。4 的光二聚化产生了 1 以及另外两个二聚产物 2 和 3。
