摘要
呋喃酮类香料在食品、烟草中应用很广。文章在无水无氧，二乙胺存在的条件下，萘化锂与丁酸作用，生成α－碳负离子丁酸锂，然后再与１，２－环氧丙烷作用，得到γ－羟基酸，经分子内脱水环化得呋喃酮，用ＩＲ、１３ＣＮＭＲ和ＧＣ／ＭＳ对其进行了研究，并对反应机理进行了讨论。
Furanones are widely used in food and tobacco,ant it is very important to study their synthesis and properties. In this paper,pure 5 methyl 3 ethyl 4, 5 dihydro 2 (3H) furanone is obtained by the reaction of the butyric acid with 1,2 epoxypropane in the presence of lithium,naphthalene and disthylamine.It is characterized by IR, 13 CNMR and GC/MS.
