investigation of global extracts from cultures of the marine deuteromycete Dendryphiella salina leads to the isolation of three novel trinor-eremophilanes esterified by branched C9-carboxylic acids, dendryphiellin B(= (+)-(1R*,2S*,7R*,8aR*)-1,2,6,7,8,8a-hexahydro-7-hydroxy-1,8a-dimethyl-6-oxonaphthalen-2-yl (6R*, 2E, 4E)-6-hydroxy-6-methylocta-2,4-dienoate; (+)-2), dendryphiellin C (=(+)-(1R*, 2S*, 7R*, 8aR*)-1
进一步研究了来自海洋氘核菌盐藻Dendryphiella salina的培养物的全球提取物,从而分离出三种被支链C 9-羧酸酯化的新型trinor-eremophilanes ,即dendryphiellin B(=(+)-(1 R *,2 S *,7 R *,8a R *)-1,2,6,7,8,8a-六氢-7-羟基-1,8a-二甲基-6-氧杂萘-2-基(6 R *,2 E,4 E) -6-羟基-6-甲基辛基-2,4-二烯酸酯;(+)- 2),树枝菌素C(=(+)-(1 R *,2 S *,7 R *,8a R*)-1,2,6,7,8,8a-六氢-7-羟基-1,8a-二甲基-6-氧代萘-2-基(6 S,2 E,4 E)-6-甲基辛基-2,4-二羟戊酸酯;(+)- 3))和树状磷脂D(=(+)-(1 R *,2 S *,7 R *,8a R *)-1,2,6,7(8,8a-hexahydro-7
