Abstract
Four new 11(15-->1)-abeotaxoids with an opened oxetane ring system, taxuyunnanines S, T, U and V (1 - 4) were isolated from the bark of Taxus yunnanensis. Taxuyunnanine S (1), is the most hydroxylated abeotaxoid discovered to date from Taxus species. The structures were determined by spectroscopic means including 1D and 2D NMR experiments.
摘要
从云南红豆杉树皮中分离出四种新的具有开环氧杂环丁烷环系统的11(15→1)-阿贝紫杉烷类化合物，即云南紫杉碱S、T、U和V（1-4）。云南紫杉碱S（1）是迄今为止从红豆杉属植物中发现的羟基化程度最高的阿贝紫杉烷类化合物。通过包括一维和二维核磁共振实验在内的光谱手段确定了其结构。
