摘要： 4,5-Secoeudesmane-type and iphionane-type compounds are sesquiterpenes with new carbon skeletons found in natrual sources in recent years.1-6 The Co-occurence of 4,5-secoeudesmanes, iphionanes and eudesmanes as natrual products suggests that 4,5-secoeudesmanes, iphionanes most likely are generated biogenetically from eudesmanes, and iphionanes are formed biogenetically by aldol reaction of 4,5-dioxosecoeudesmanes.1,4,6,7 The study on the synthesis of this two kind of new sesquiterpenes has not been reported in the literature.
