The total synthesis of (±) pinguisone 1, the sterically crowded unusual [5-6] fused-ring sesquiterpene, was accomplished by synthetic elaboration of the 3β,3aβ,7,7aβ-tetramethylbicyclo [4.3.0] non-6-en-1-one prepared by acid catalyzed rearrangement of the easily accessible 1,4β,5,9-tetramethylbicyclo [3.3.1] nonan-9-hydroxy-2-one . This rearrangement constitutes an example of the scarcely observed
通过立体合成3β,3aβ,7,7aβ-四甲基双环[4.3.0] non-6-en来完成(±)品吉松1(空间拥挤的不寻常[5-6]稠环倍半萜烯)的总合成。通过酸催化的易获得的1,4β,5,9-四甲基双环[3.3.1] nonan-9-hydroxy-2-one的-1重排制备。这种重排构成了几乎未观察到的羰基向电子缺乏中心的1,2位移的一个例子。
