The silicon/germanium/tin analogues of the lily‐of‐the‐valley odorants lilial (rac‐1 a), compounds rac‐1 b, rac‐1 c, and rac‐1 d, and bourgeonal (2 a), compounds 2 b, 2 c, and 2 d, were synthesized and characterized for their olfactory properties, including GC–olfactometry studies. Compounds rac‐1 a–c and 2 a–c possess a typical lily‐of‐the‐valley odor, whereas the stanna‐analogues rac‐1 d and 2 d
百合的最谷气味剂铃兰醛(的硅/锗/锡类似物外消旋- 1),化合物的外消旋- 1b中,外消旋-图1c,和外消旋- 1 d和bourgeonal(2),化合物合成了2 b,2 c和2 d,并对其嗅觉特性进行了表征,包括GC嗅觉研究。化合物外消旋- 1 - c ^和2 - ç具有一个典型的百合的最谷气味,而stanna -类似物外消旋‐ 1 d和2 d,尽管有些花香,但显然不再属于铃兰科。在所研究的两个系列的碳/硅/锗/锡类似物中,铃兰的气味以碳<硅<锗<锡的顺序降低。产生与hOR17-4的稳定四环素调节表达的HEK293细胞系中通过分析重组hOR17-4活化外消旋- 1 - d和2 - d通过使用钙2+成像。Bourgeonal(2)显示出最高的效力激活,而铃兰醛(外消旋- 1)和硅杂bourgeonal(2b的)展示出较低的激活潜能。硅杂铃兰醛(外消旋-图1b),GERMA-铃兰醛(外消旋-
