四种新的酚苯酚二萜化合物 [(3R*, 6R*, 9R*, 1OS*)-sphenloba-13E, 16E, 18-trien-4-one, (3R*, 6R*, 9R*, 10S*)-18-羟基酚苯酚巴-13E, 16E-dien-4-one (3R*, 6R*, 9R*, 10S*)-sphenoba-13E、17-dien-4-one 和 (6R*,9R*,10S*)-3 alpha, 4 alpha-epoxysphenoba-13(14), 16E-dien-15, 18-diol] 与两种先前已知的酚烷一起从地钱 Anastrophyllum donnianum 中分离出来 [(6R*, 9R*, [10S*)-3α、4α-环氧酚巴-13E、16E-二烯-18-醇和(6R*,9R*,10S*)-3α、4α-环氧酚巴-13E,17-二烯]和四种已知的倍半萜类化合物。使用光谱方法建立结构。报告了新化合物的 H-1 和 C-13 NMR 数据以及 3 α-乙酰氧基双环germacra-1(10), 4-二烯的 C-13 数据。版权所有 (C) 1996 爱思唯尔科学有限公司
Four new sphenolobane diterpenoids [(3R*, 6R*, 9R*, 1OS*)-sphenoloba-13E, 16E, 18-trien-4-one, (3R*, 6R*, 9R*, 10S*)-18-hydroxysphenoloba-13E, 16E-dien-4-one (3R*, 6R*, 9R*, 10S*)-sphenoloba-13E, 17-dien-4-one, and (6R*,9R*,10S*)-3 alpha, 4 alpha-epoxysphenoloba-13(14), 16E-dien-15, 18-diol] have been isolated from the liverwort Anastrophyllum donnianum together with two previously known sphenolobanes [(6R*, 9R*, 10S*)-3 alpha, 4 alpha-epoxysphenoloba-13E, 16E-dien-18-ol and (6R*,9R*,10S*)-3 alpha, 4 alpha-epoxysphenoloba-13E,17-diene] and four known sesquiterpenoids. Structures were established using spectroscopic methods. H-1 and C-13 NMR data of the new compounds and C-13 data of 3 alpha-acetoxybicyclogermacra-1(10), 4-diene are reported.
