Abstract Four new metabolites, 10-oxo-dihydrobotrydial, 4β-acetoxy-9β-10β-15α-trihydroxyprobotrydial, β - O -methyldihydrobotrydialone and α - O -methyldihydrobotrydialone, were isolated from a shake culture of Botrytis cenerea . The second compound, a tricyclic sesquiterpene, is a key biosynthetic intermediate and sheds light on the last steps of the biosynthesis of botrydial derivatives. A higher
摘要 从 Botrytis cenerea 的振荡培养物中分离出四种新的代谢物,10-oxo-dihydrobotrydial、4β-acetoxy-9β-10β-15α-trihydroxyprobotrydial、β-O-methyldihydrobotrydialone 和 α-O-methyldihydrobotrydialone。第二种化合物是三环倍半萜烯,是一种关键的生物合成中间体,揭示了葡萄二醛衍生物生物合成的最后一步。在分离的代谢物中观察到更高的氧化水平。通过对天然化合物及其衍生物的广泛 NMR 研究阐明了结构。
