Abstract: Nine new compounds of [α-Alkyl-β-(2,2,3-Trimethyl-3-Cyclopentenyl)Ethyl] acetate with alkyls as methyl, ethyl, n-propyl, isopropyl, n-butyl, sec-butyl, isobutyl, n-pentyl, isopentyl have been synthesized from α-pinene through a series of reaction of epoxidation, rearrangement, Grignard reagents addition and esterification etc. These compounds have been identified by GC, MS, IR and NMR.

Key words: [ α-alkyl-β-(2, 3-trimethyl-3-cyclopentenyl)ethyl] acetate, α-pinene, epoxidation, rearrangement, Grignard reaction, esterification

摘要： 以α-蒎烯为原料，经环氧化等一系列反应，将α-烷基-β-（２，２，３-三甲基-３-环戊烯基）乙醇酯化得到乙酸［α-烷基-β-（２，２，３-三甲基-３-－环戊烯基）乙基］酯（烷基为Me，Et，n-pr，i-Pr，n-Bu，i-Bu，s-Bu，n-Am，i-Am）共9个新化合物，通过波谱及色谱确定了它们的结构及含量。
