9a-dimethylnaphtho[2,1-b]furans) have been synthesized and subjected to sensory evaluation. Threshold data and odor determination give an enlarged insight into the structure-activity relationship (SAR) in ambrox-type ambergris fragrances. As a general conclusion, the accumulation of axial CH3 groups in the tricyclic ethers 1–12 leads to the strongest receptor affinity.
非对映异构体18-norrambrox和19-norambrox((6α)-和(6β)-dodecahydro-3a,6,9a-三甲基萘[2,1- b ]呋喃)和相应的18,19-dior -衍生物(dodecahydro-3a,9a-二甲基萘[2,1- b ]呋喃)已经合成并进行了感官评估。阈值数据和气味测定可提供对ambrox型龙涎香香料的结构-活性关系(SAR)的深入了解。作为一般的结论,轴向CH积累3个在三环基团醚1 - 12通向最强受体的亲和力。
