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性,与天然产物非常相似的2,3-二氢呋喃。这些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,R.sub.1是具有1至4个碳原子的烷基,R.sub.2是氢原子或具有1至6个碳原子的烷基,而R.sub.3和R.sub.4是氢原子或甲基基团。这些2,3-二氢呋喃化合物可用于制备香料组合物和带香气的物品,并可与已知香料材料一起使用以增强其香气。
