对䓝烷-1-胺及其衍生物的合成与除草活性研究
摘 要
松节油是从松科属植物分泌的松脂中提取的一种精油。它是世界上产量巨大、价格低廉的精油之一。alpha;-蒎烯作为松节油的重要组分之一，具有良好的结构化学反应特性。它能进行加成、异构化、氧化、聚合、热裂解等多种反应，生成大量的衍生化合物。此次研究利用Ritter反应，将醇类化合物转化为胺类化合物，利用醛胺缩合反应合成席夫碱。以松节油提取物alpha;-蒎烯为主要原料，经过Ritter反应、酸催化脱乙酰基、碱催化水解、加氢还原、醛胺缩合、NaBH4还原反应，再经过柱层析分离纯化，得到一些列对䓝烷-1-仲胺类化合物。通过除草活性测试，对比研究对䓝烷-1-胺及其衍生物的除草活性，为新型除草剂的开发和利用奠定基础。

Synthesis and herbicidal activity of paraffine-1-amine and its derivatives
Abstract
Turpentine is an essential oil extracted from turpentine secreted by pineal plants. It is one of the world#39;s largest and cheapest essential oils. As an important component of turpentine, alpha;- pinene has good structural chemical reaction characteristics. It can be used in addition, isomerization, oxidation, polymerization, pyrolysis and other reactions to generate a large number of derived compounds.In this study, Ritter reaction was used to convert alcohols into amines, and aldehyde amine condensation was used to synthesize Schiff base. A series of paraffine-1-secondary amines were obtained by Ritter reaction, acid catalyzed deacetylation, alkali catalyzed hydrolysis, hydrogenation reduction, aldoamine condensation, NaBH4 reduction and column chromatography by using turpentine extract alpha; - pinene as the main raw material. Through the test of herbicidal activity, the herbicidal activity of Paraffine-1-Amin and its derivatives was compared, which laid a foundation for the development and utilization of new herbicides.
