Abstract
Two steroids, haliclostanone sulfate (1) and halistanol sulfate (3), were isolated from a Haliclona sp. marine sponge. The structure of the new compound 1 was established based on its spectroscopic data and the properties of a pentaacetate derivative 2. Compound 1 is unique in that it possesses the rare cis C/D ring junction precedented only in marine sterols, contignasterol (4) and xestobergsterols A (5), B (6), and C (7).
摘要
从一种Haliclona属海洋海绵中分离出两种甾体化合物，硫酸卤氯甾酮（1）和硫酸卤甾醇（3）。新化合物1的结构是根据其光谱数据和五乙酸酯衍生物2的性质确定的。化合物1的独特之处在于它具有罕见的顺式C/D环连接，这种结构仅在海洋甾醇、邻锥甾醇（4）和西托贝格甾醇A（5）、B（6）和C（7）中出现过。
