illustrating the utility and scope of this reaction. The olfactory properties of the synthesized [4.3.3]propellanes as well as of the original target structures 10, 33, and 34, prepared from (−)-12 and (−)-15, are discussed. Especially the pronounced ambra odor of (−)-17 vividly contradicts the ‘triaxial rule of amber sensation' and provides new insight into the structural requirements for ambra odorants

香紫苏内酯(1)与Eaton'反应的副产物24提供了对这种重排的机械学见解。的试剂。然后,将碳正离子的重排是在四个相关的合成[4.3.3]螺桨40 - 43,示出了该反应的效用和范围。讨论了由(-)- 12和(-)- 15制备的合成[4.3.3]
丙炔以及原始靶结构10、33和34的嗅觉特性。尤其是(−)- 17的明显的安布拉香气与“琥珀感的三轴法则”明显矛盾,并为安布拉香气的结构要求提供了新的见识。
