Coumarin (1), the putative natural product isolated from Colchicum decaisnei, has been shown, by spectroscopic analysis and total synthesis, to be isoeugenetin methyl ether (2a), a synthetic derivative of the isoeugenetin (2b), isolated from Eugenia carvophyllata.
香豆素(1)是从秋水仙(Colchicum decaisnei)分离得到的推定天然产物,通过光谱分析和全合成已显示为异丁香素甲基醚(2a),异丁香素(2b)的合成衍生物,其分离自番樱桃(Eugenia carvophyllata)。
