2,3-Dihydrofurans having highly desirable odor characteristics closely mimicking that of natural products are provided herein. The 2,3-dihydrofurans correspond to the formula ##STR1## wherein R' is an alkyl group having from 1 to 4 carbon atoms, R** is an alkyl group having from 1 to 5 carbon atoms, R.sub.1 is an alkyl group having from 1 to 4 carbon atoms, R.sub.2 is hydrogen or an alkyl group having from 1 to 6 carbon atoms, and R.sub.3 and R.sub.4 are hydrogen or a methyl group. The 2,3-dihydrofuran compounds are useful in the preparation of fragrance compositions and fragranced articles and can be employed in conjunction with known fragrance materials to augment or enhance the aromas thereof.
本文提供了具有高度理想气味特征的2,3-二氢呋喃,其特征与天然产物非常接近。2,3-二氢呋喃对应于以下式子:##STR1## 其中,R'是具有1至4个碳原子的烷基,R**是具有1至5个碳原子的烷基,R1是具有1至4个碳原子的烷基,R2是氢或具有1至6个碳原子的烷基,R3和R4是氢或甲基。这些2,3-二氢呋喃化合物在香料组合物和带香物品的制备中非常有用,可以与已知的香料材料一起使用,以增强其香气。
