On the basis of exhaustive 1H-and 13C-nuclear magnetic resonance (NMR) spectral studies and chemical transformations, the structure of an iridoid glucoside formerly designated as 5-epideoxyloganic acid, isolated from Nepeta cataria L., has been revised to (1R, 5R, 8S, 9S)-deoxyloganic acid, which is renamed 1, 5, 9-epideoxyloganic acid. The absolute configuration of this glucoside was established by its chemical conversion to an antipode of boschnialactone.
在详尽的 1H 和 13C 核磁共振(NMR)光谱研究和化学转化的基础上,从 Nepeta cataria L.中分离出的一种鸢尾甙的结构被修正为 (1R, 5R, 8S, 9S)-deoxyloganic acid,并重新命名为 1, 5, 9-epideoxyloganic acid。这种苷的绝对构型是通过其化学转化为一种反式波斯内酯而确定的。
