Treatment of glycocitrine-II (1), one of the acridone alkaloids having an ortho-prehylphenol moiety isolated from Citrus plants, with m-chloroperbenzoic acid (m-CPBA) in dichloromethane gave a novel oxidation product 2, along with the known cyclization products 3 and 4. The structure of 2 was elucidated by spectrometric and X-ray crystal-lographic analyses.
糖精酸-II(1)是一种从柑橘类植物中分离出的具有
邻苯基苯酚部分的
吖啶生物碱,在
二氯甲烷中与
间氯过氧苯甲酸(m-CPBA)反应,得到一种新的氧化产物2,以及已知的环化产物3和4。通过光谱分析和X射线晶体学分析,阐明了2的结构。
