报道了对桉烷倍半萜天然产物3-furanoeudesmene的首次全合成.从商品化手性试剂(+)-马鞭烯酮出发,以关环烯烃复分解反应及三步法呋喃环构建为关键步骤,总共八步反应实现了目标分子的立体选择性合成.通过比对合成的目标分子的旋光值与天然产物的旋光值,确定出天然产物的绝对构型.
The first full synthesis of 3-furanoeudesmene, a natural product of eucalyptus sesquiterpenoids, was reported.From the commercially available chiral reagent (+) - whiprinone, the key step was to establish the metathesis reaction of cycloolefin and the three-step furan ring, A total of eight steps to achieve the target molecule stereoselective synthesis by comparing the optical rotation of the target molecule and the optical rotation of the natural product to determine the absolute configuration of the natural product.
