Starting with (+)-nopinone (3); (R)-(-)-Cryptone (1) and (S)-(-)-4-isopropenyl-2-cyclohexen-1-one (2) were synthesized in five steps and 42% overall yield, and four steps and 49% overall yield, respectively.
从 (+)-nopinone (3) 开始,分别用五个步骤合成了 (R)-(-)-Cryptone (1) 和 (S)-(-)-4-isopropenyl-2-cyclohexen-1-one (2),总产率分别为 42%和 49%。
