Succinct and stereoselective: A high‐yielding two‐step indole ring installation comprising the Stille cross‐coupling and a PdII‐mediated oxidative heterocyclization was exploited in a concise total synthesis of paspalinine. The trans‐anti‐trans CDE fused ring system of the heptacyclic natural product was established highly stereoselectively through hydroxy‐directed cyclopropanation and allylic selenoxide
简洁和立体选择性:在简明的全合成帕斯帕林中,采用了包括斯蒂勒交叉偶联和Pd II介导的氧化杂环的高产率两步吲哚环装置。所述TRAN S-反-反式CDE稠合的七环天然产物的环系统,通过羟基导向环丙烷和烯丙基硒亚砜的重排成立高度立体选择性。
