2-Methylheptadecane (I) is the sex pheromone of the family Arctiidae (tiger moth) and was isolated by Roelof and Carde and assigned structure I on the basis of spectral data. Haque et al. isolated a granular white solid (m.p. 80 °C) from the ether extract of dried and powdered plant of Parthenium hysterophorous L. (Compositae) and proposed its structure, 14-methylpentadecan-3-one (II) on the basis of spectroscopic data. We report herein a short and facile synthesis of these compounds.
2-甲基庚十七烷(I)是家族Arctiidae(虎蛾)的性信息素,由Roelof和Carde分离并根据光谱数据确定结构I。Haque等人从Parthenium hysterophorous L.(菊科)的干燥和粉末植物的醚提取物中分离出一种颗粒状白色固体(熔点80°C),并根据光谱数据提出其结构,14-甲基十五烷-3-酮(II)。我们在此报告这些化合物的简短和简便合成方法。
