| 摘 要： | 以乙酰基吡嗪和异戊酸乙酯为原料，合成了2．异丙基-3-羟基-3-甲基-3-吡嗪丙酸乙酯(1)。其结构经^1H NMR和MS表征。加香评吸实验表明其对烤烟型卷烟的香气有很好的提升作用，可以掩盖杂气，余味更舒适。烟气分析结果证明，1是一种前体香料，在燃烧状况下能发生裂解反应，释放出乙酰基吡嗪。

| Abstract: | Ethyl 2-isopropyl-3-hydroxy-3-methyl-3-pyrazinylpropionate(1) was synthesized from (2-acetylpyrazine) and ethyl isovalerate in 45% yield. The structure was characterized by ~1H NMR and MS. The experamental results showed that 1 can increase aroma of tobacco smoke and was a flavor precursor, which released 2-acetylpyrazine by cracking reaction during smoking. |
