从孟加拉采集的马占相思的叶中分离得到一种新的C20天然产物--金合欢酮(1)。通过光谱分析和X-射线单晶分析确定了化合物1的结构。环戊二烯酮(1)具有与萜类相关的四环骨架,含有20个碳,具有生物遗传学上不寻常的结构特征:(I)在A环的C-3和C-4位置上有邻近的C1-分支,和(Ii)在雄酮类组装中的环戊酮D环,在C-13位置缺少甲基。
A novel C20 natural product, acacienone (1), was isolated from the leaves ofAcacia mangiumcollected in Bangladesh. The structure of compound1was elucidated by spectral studies and X-ray crystallographic analysis. Acacienone (1) possesses a terpenoid-related tetracyclic framework containing 20 carbons with biogenetically unusual structural features: (i) vicinal C1-branches at the C-3 and C-4 positions in the A ring, and (ii) a cyclopentenone D ring in an androsterone-like assembly, lacking a methyl group at the C-13 position.
