Abstract
A new alkaloid (1a), named pandamarilactonine-H, which possesses a methyl-2-(pyrrolidin-2-yl)acetate function, was isolated from the roots of Pandanus amaryllifolius. Eleven known alkaloids were also isolated. Unambiguous assignment of the structure of 1a, including the absolute configuration, was accomplished by spectroscopic analysis and total synthesis of its enantiomer.
摘要
从马兜铃科植物天仙藤根部分离得到一种新的生物碱（1a），命名为 pandamarilactonine-H，它具有甲基-2-（吡咯烷-2-基）乙酸酯功能。还分离得到了 11 种已知生物碱。通过对其对映异构体的光谱分析和全合成，明确了 1a 的结构，包括绝对构型。
