[structure: see text] Latonduines A (6) and B (7), two new alkaloids with unprecedented heterocyclic skeletons, have been isolated from the Indonesian marine sponge Stylissa carteri. The structures of the latonduines were elucidated by analysis of spectroscopic data and confirmed by the total synthesis of latonduine A (6). It is proposed that ornithine is the biogenetic precursor to the aminopyrimidine
[结构:见正文] Latonduines A(6)和B(7)是两种新的具有前所未有的杂环骨架的生物碱,已从印度尼西亚海洋海绵Stylissa carteri中分离出来。通过分析光谱数据阐明了latonduines的结构,并通过latonduine A的全合成对其进行了证实(6)。提出鸟氨酸是拉托二胺的氨基嘧啶片段的生物遗传前体。
