摘要: 将诺卜醇(Nopol)分别在甲醇和乙醇中臭氧化后,再进行还原性水解,溶液经处理后进行了GC-MS分析。对所得质谱数据进行解析,确定了6个主要产物的结构,它们是cis- 2,2-二甲基 3-(β-羟基丙酰基)环丁烷乙醛、3 羟基cis-2,2-二甲基 3-(β-羟基丙酰基)环丁烷乙醛、1 羟基cis-2,2-二甲基 3-(β-羟基丙酰基)环丁烷乙醛、cis-2,2-二甲基 3-(β-羟基丙酰基)环丁烷乙醛缩二甲醇、cis-2,2-二甲基 3 (β 羟基丙酰基)环丁烷乙醛缩二乙醇和2,2 二甲基 3-(β-羟基丙酰基)环丁酮。分析结果表明:这6个主要产物都是诺卜醇分子中双键断裂后所形成的四元环类化合物,诺卜醇臭氧化时除了碳碳双键、叔氢被氧化外,还伴有其它更深层次的反应。

Abstract: Nopol was ozonized in methanol and ethanol respectively, followed by reductive hydrolyzation and GC MS analysis.The MS data was analyzed, and structures of6 main products have been identified, namely:cis-2, 2-dimethyl 3-(β-hydroxypropionyl) cyclobutaneethanal, 3 hydroxy cis-2, 2-dimethyl 3-(β-hydroxypropionyl) cyclobutaneethanal, 1 hydroxy cis-2, 2-dimethyl 3-(β-hydroxypropionyl) cyclobutaneethanal, cis cis-2, 2-dimethyl 3-(β-hydroxypropionyl) cyclobutaneacetaldehyde dimethyl acetal, cis-2, 2-dimethyl 3-(β-hydroxypropionyl) cyclobutaneacetaldehyde diethyl acetal and 2, 2-dimethyl 3-(β-hydroxypropionyl) butanone.The results showed:1)The 6 main products are all four member ring compounds produced through the cleavage of double bond of nopol;2)Accompany with oxidations of the double bond and tertiary hydrogen in the ozonization, there are other reactions at more in depth levels.

Key words: nopol, ozonization, GC-MS analysis, four-member-ring compound
