降茄二酮的合成及在烟草加香中的应用

Synthesis of Solandione and its Application in Tobacco Flavoring

降茄二酮是烟草中重要的香味成分，其对卷烟香味有重要贡献［１］。报道了以异戊醛为起始原料经烯胺化反应、与丁烯酮缩合、水解及与乙酰甲叉基三苯基膦缩合制备降茄二酮的合成工艺，对合成工艺进行了改进，对产品结构进行了ＩＲ及１Ｈ－ＮＭＲ确证，并对产品在烟草中的作用进行了研究。结果表明降茄二酮在烟气中的作用是增加烟香，使烟气醇厚，提高香气品质，是烟草加香有发展前途的重要香味物质。

This paper reported a synthetic technology of preparation of solandione through enainic reaction,condensation with methyl vinyl ketone,hydrolysis and wittg reaction starting from iso amyl aldehyde. The synthetic technology was improved ,and end product structure was confirmed by the IR, 1H-NMR.The effects of solandione in tobacco was also studied .The application experiments show that solandione can enhance tobacco aroma,make tobacco smoke smooth and mild.
