Abstract：
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.
