γ-lactonic cembranolides were isolated from the gorgonian Eunicea succinea collected near Palomino Key, Puerto Rico on July,1989. The structure of two were determined from spectral data and chemical correlation experiments to be those of known 12,13-bisepleupalmerin (1) and eunicin (3). The structure of the third metabolite was deduced from spectroscopic data and from chemical degradation experiments to
从1989年7月在波多黎各的帕洛米诺基附近收集的高古猿Eunicea succinea中分离出三种简单的γ-内酰胺基乙内酰胺。根据光谱数据和化学相关性实验确定了两者的结构,即已知的12,13-双酚联蛋白(1)和尤尼克霉素(3)的结构。根据光谱数据和化学降解实验推论出第三种代谢物的结构为恩洛利德(2),一种先前未描述的γ-内酯西布罗奈德。1989年3月提取了在Desecheo岛波多黎各附近收集的大戟属的新鲜标本,除已知的本安普兰二萜二萜紫杉醇乙酸酯外,还提供了日光卤化物(4)。
