Three new rearranged ent-kaurane-type diterpenoids (1-3) and seven new ent-kaurane-type diterpenoids (4-10) have been isolated from the liverwort Jungermannia atrobrunnea. Their structures were determined by extensive spectroscopic techniques and X-ray crystallographic analysis. The absolute configurations of these compounds were clarified by CD spectroscopic studies. Compound 1 is the first example of a rearranged ent-kaurane diterpenoid possessing a peroxide bridge.
从苔类植物深褐叶苔(Jungermannia atrobrunnea)中分离出了3个新的重排对映-贝壳杉烷型二萜(1-3)和7个新的对映-贝壳杉烷型二萜(4-10)。通过广泛的光谱技术和X射线晶体学分析确定了它们的结构。通过圆二色光谱研究阐明了这些化合物的绝对构型。化合物1是具有过氧化物桥的重排对映-贝壳杉烷二萜的首个实例。
