Two new sesquiterpenes belonging to a novel oxacyclic structural type of chamigrene skeleton, oxachamigrene (1) and 5-acetoxyoxachamigrene (2), have been isolated from the red alga Laurencia obtusa. The structures of the compounds were determined on the basis of spectroscopic evidence. A biogenetic route for these metabolites has been proposed.
从红藻钝形劳伦氏藻中分离出了两种新的倍半萜，它们属于一种新型的具有菖蒲烯骨架的氧杂环结构类型，即氧杂菖蒲烯（1）和5-乙酰氧基氧杂菖蒲烯（2）。这些化合物的结构是根据光谱证据确定的。已提出了这些代谢产物的生源合成途径。
