An unprecedented trinorcassane diterpenoid and a cassane furanoditerpenoid were isolated from the seeds of Caesalpinia minax. It is the first example of dicylic cassane-type trinorditerpenoid, which is different from reported 16- or 17-norcassane diterpenoids. The structure of the compounds was elucidated on the basis of 1D and 2D NMR analysis. Biosynthesis pathways are postulated, and this pathway was supported by semi-synthesis.
从少花云实属植物的种子中分离出了一种前所未有的三降羽扇豆烷二萜和一种羽扇豆烷呋喃二萜。这是双环羽扇豆烷型三降二萜的首个实例，与已报道的16-或17-降羽扇豆烷二萜不同。基于一维和二维核磁共振分析阐明了这些化合物的结构。推测了生物合成途径，并且该途径得到了半合成的支持。
