2]decane skeleton, has been accomplished starting from 1-methoxy-4,5,8-endo-trimethylbicyclo[2.2.2]oct-5-en-2-one by a rearrangement strategy including the formal bridgehead substitution of this methoxy group by hydrogen on the basis of a pinacol-type rearrangement and the double ring-enlargement of this product to give 6,7,10-exo-trimethyl-bicyclo[4.2.2]dec-7-en-2-one via the bicyclo[3.2.2]non-6-en-2-one
(1-)-nakafuran-8(一种含有双环[4.2.2]
癸烷骨架的
呋喃倍半萜烯)的首次全合成从1-甲氧基-4,5,8-内-三甲基双环[2.2.2] oct开始-5-en-2-one通过重排策略,包括在
频哪醇型重排和该产物的双环扩大的基础上,用氢将该甲氧基基团用氢正式桥头取代,得到6,7,10- exo -三甲基-双环[4.2.2] dec-7-en-2-one通过双环[3.2.2] non-6-en-2-one。
