(2), (1R,10R)-9beta-hydroxyaromadendrane (3), (1S,10S)-allo-aromadendran-9-one (4), (1R,10R)-aromadendran-9-one (5) and aromadendra-1,9-diene (6). Each congener was incubated with the fungus Curvularia lunata ATCC 12017 in two different growth media. All the substrates except the deoxy compound 6 underwent a simple redox reaction. Ketone 5 additionally experienced remote hydroxylation while analogue
从 Hyptis verticillata (Labiatae) 中分离出的天然倍半萜烯角鲨烯酮 (1) 被合成还原为五种类似物,被鉴定为 (1S,10S)-9alpha-羟基-allo-aromadendrane (2), (1R,10R)- 9beta-hydroxyaromadendrane (3)、(1S,10S)-allo-aromadendran-9-one (4)、(1R,10R)-aromadendran-9-one (5) 和aromadendra-1,9-diene (6)。每个同源物在两种不同的生长培养基中与真菌 Curvularia lunata ATCC 12017 一起孵育。除脱氧化合物 6 外的所有底物都发生了简单的氧化还原反应。酮 5 还经历了远程羟基化,而具有共轭二烯系统的类似物 6 被最广泛地代谢。这里介绍的基材和产品,但一个,都是新颖的。
