The first total synthesis of goniothalesdiol, a dihydroxylated tetrahydrofuran isolated from Goniothalamus borneensis (Annonaceae), and its 7-epimer is described starting with d-mannitol. The key step of these syntheses is palladium(II)-catalyzed oxycarbonylation of unsaturated triols with d-lyxo and d-xylo configuration, respectively, which allowed efficient construction of the tetrahydrofuran ring
goniothalesdiol的第一全合成中,二羟基化四氢呋喃分离自哥纳香属囊螺(番荔枝),和其7-差向异构体被描述起始d甘露醇。这些合成的关键步骤分别是钯(II)催化具有d- lyxo和d- xylo构型的不饱和三醇的氧羰基化反应,从而可以在新形成的立体异构中心高效构建具有优良苏氨酸选择性的四氢呋喃环。
