The structures of three new compounds, glycinoeclepins A, B, and C, isolated from the hatch-stimulating extracts of kidney beans for the soybean cyst nematode, have been determined. The structures were resolved by using spectroscopic methods, especially by the difference NOE techniques, and confirmed by the X-ray diffraction analysis. These structures are characterized by (1) migration of two methyl
已经确定了从大豆胞囊线虫的芸豆孵化刺激提取物中分离出的三种新化合物甘氨酸环素 A、B 和 C 的结构。通过使用光谱方法,特别是通过差异 NOE 技术解析结构,并通过 X 射线衍射分析确认。这些结构的特点是 (1) C 和 D 环中两个甲基的迁移,(2) B 环氧化裂解失去一个碳原子和 (3) 7-氧杂双环 [2.2.1] 的存在与环阿烷烃相比,A环中的庚烷系统被视为戊烷-(GEA)或去甲三萜(GEB和GEC)。
