two new 2-acylcyclopentene-1,3-dione derivatives, were isolated from the fruiting bodies of the Basidiomycete Hygrophorus chrysodon, and their structures were established by spectroscopic data and synthesis of compound 2. They represent the first examples of 2-acylcyclopentene-1,3-diones found in mushrooms and suggest an unprecedented biosynthetic pathway, starting from fatty acid derivatives. Initial
从巴西芦苇(Basidiomycete Hygrophorus chrysodon)的子实体中分离出两种新的2-酰基环戊烯-1,3-二酮衍生物Chrysotriones A(1)和B(2),并通过光谱数据和化合物2的合成确定了它们的结构。它们代表了蘑菇中发现的2-酰基环戊烯-1,3-二酮的第一个实例,并提出了从脂肪酸衍生物开始的前所未有的生物合成途径。初步测试表明,金银三酮对镰状镰刀菌(Fusarium verticillioides)具有抗真菌活性,镰刀菌是全世界栽培植物的常见病原体之一。
