(S(p))-(+)-Spiniferin-1 and (R(p))-(-)-spiniferin-1, a pair of unusual marine natural products with planar chirality, were firstly synthesized via a polyfluoroalkanosulfonyl fluoride induced homoallylic carbocation rearrangement reaction. The chiral resolution and palladium-catalyzed beta-H elimination of allylic alcohol derivatives were considered as the key steps of these divergent syntheses.
(S(p))-(+)-Spiniferin-1和(R(p))-(--- spiniferin-1)是一对具有平面手性的异常海洋天然产物,是首先通过多氟链烷磺酰氟诱导的均聚物合成的碳阳离子重排反应。手性拆分和钯催化的烯丙基醇衍生物的β-H消除被认为是这些不同合成的关键步骤。
