From the leaves of Oncinotis tenuiloba STAPF, a novel polyamine alkaloid, tenuilobine (9), was isolated. This paper presents the synthesis of 9, as well as the base-catalyzed Zip reaction of 9, leading to the transamidation product isotenuilobine (10). The structure of 10 was further confirmed by 2D-NMR correlation spectroscopy. For analytical purposes, the bis-polyamines 9 and 10 were converted into
从Oncinotis tenuiloba STAPF的叶子中,分离出一种新型的多胺生物碱tenuilobine(9)。本文介绍了合成的9,以及碱催化邮编的反应9,导致转酰氨产物isotenuilobine(10)。通过2D-NMR相关光谱进一步确认了10的结构。为了分析目的,将双聚胺9和10分别转化为其五乙酰基衍生物12和11,它们可以通过反相HPLC容易地分离。
