A total synthesis of pterosines B and C is reported. Starting with a fourfold substituted benzene derivative, the introduction of the remaining substituents is mainly based on Sonogashira couplings followed by different transformations of the ethyne moiety. The key step is a photochemical ring-closure of an α-mesyloxy ketone forming the 1-indanone skeleton.
报道了蝶呤 B 和 C 的全合成。从四重取代的苯衍生物开始,其余取代基的引入主要基于 Sonogashira 偶联,然后是乙炔部分的不同转化。关键步骤是形成 1-茚满酮骨架的 α-甲磺酰氧基酮的光化学闭环。
