The first total synthesis of (+)-decipienin A has been achieved in 4% overall yield in seven steps from (+)-dihydrocarvone, thus confirming the stereostructure proposed by Holub et al. (Holub, M.; Budesinsky, M. Phytochemistry1986, 25, 2015–2026) for this lactone and the original assignments should be corrected as indicated in by formula (a) (6αH,7αH,10αmethyl-eudesman-6,12-olide). Two different strategies
从(+)-二氢香芹酮分七个步骤,以4%的总收率实现了(+)-地精蛋白A的首次全合成,从而证实了Holub等人提出的立体结构。(赫鲁伯,M。; Budesinsky,M.植物化学1986,25,2015年至2026年),用于本内酯和原来的分配应当如在由式表示来校正的(a)(6αH,7αH,10αmethyl-eudesman-6,12- olide)。使用了两种不同的策略,第一种尝试通过C-6位置的官能化来构建α-羟基-γ-内酯部分,第二种涉及在合成的最后步骤中引入C-11羟基方案。
