Abstract

Two new diaryl ethers, named phomopside A (1) and B (2), together with known excelsione (3) were isolated from the mangrove endophytic fungus Phomopsis sp. (ZZF08) obtained from the South China Sea coast. The structure of 1 was elucidated by NMR spectroscopy and confirmed by X-ray crystallography. Compounds 2 and 3 were identified by NMR spectroscopy and comparing the spectroscopic data with literature values. In addition, the plausible biogenetic path of 1, 2 and 3 is discussed.

摘要

从中国南海海岸采集的红树林内生真菌拟茎点霉属（ZZF08）中分离出两种新的二芳基醚，分别命名为拟茎点霉A（1）和B（2），以及已知的卓越菌素（3）。通过核磁共振光谱法阐明了1的结构，并通过X射线晶体学进行了确证。通过核磁共振光谱法并将光谱数据与文献值进行比较鉴定出了化合物2和3。此外，还讨论了1、2和3可能的生源合成途径。
