The qualitative analysis of the volatiles emitted from tea plants infested by Ectropis obliqua Prout with GC-MS or zNoseTM showed the similar results, however the relative contents of-3-hexen-1-ol,benzyl nitrile,indole,-caryophyllene obtained from both showed a certain difference.

结果表明：GC-MS与zNoseTM对茶尺蠖取食诱导的茶树挥发物的定性分析结果差别不大；但两者测定茶尺蠖取食诱导的茶树挥发物中顺-3-己烯醇、苯乙腈、吲哚、反-石竹烯等4种组分的相对含量有一定差异。

This thesis is constituted by four parts: In the first part a summarization is given on the main total synthetic methods of isoflavones, for example, deoxybenzoin method which generally involves two steps wherein a phenol is reacted in the presence of a Lewis acid with phenylacetic acid to generate an intermediate deoxybenzoin which is then cyclized with a one carbon electrophile.

本论文主要工作包括四部分：第一章综述了近年来全合成异黄酮的主要方法：脱氧安息香法，是以多羟基苯酚与苯乙酸或苯乙腈在Lewis酸存在下，反应生成中间体脱氧安息香，然后再与亲电碳试剂进行关环反应生成异黄酮。

Some useful fluorine-containing intermedi-ates were synthesized by the reaction of activated methylenecompounds or silyl enol ether with 2,2-dihydropolyfluoro-alkanoates or 2-hydropolyfluoroalk-2-enoates in the presenceof different bases.

进一步研究表明，在氢化钠的作用下，苯乙腈，苄基苯基甲酮也可以与2-氢多氟-2-烯酸乙酯发生亲核加成反应，苄基苯基甲酮的加成中间体经多聚磷酸环化，得到了间位氟烷基取代的α-萘酚衍生物。

However, they can minimise the chances of this happening by releasing large amounts of a pheromone called phenylacetonitrile.
