ethers. Several bicyclic adducts were prepared in good to excellent yields (18–99%). Evaluation of NHC–Au complexes allowed to reach a TOF of 300 h–1. The evaluation for the organoleptic properties of [4.1.0]-bicyclic ethers were compared with the unprecedented properties of the 1,6-enyne precursors. Evaluations of starting materials showed a great interest in these structures with various olfactory facets

金型催化剂表现出优异的活性,可生成轻质双环烯醇醚。制备了几种双环加合物,产率非常好(18-99%)。NHC-Au 复合物的评估允许达到 300 h-1 的 TOF。[4.1.0]-双
环醚的感官特性评估与 1,6-烯炔前体前所未有的特性进行了比较。对起始材料的评估显示出对这些具有各种嗅觉面的结构的极大兴趣。在这项研究中,
