(+)-sorangicin A的正式合成是通过两条独立的途径完成的。这两种方法都具有交叉复分解反应,形成C29-C30键,得到双环醚/四氢吡喃片段。将二氢吡喃片段与分子其余部分结合的C15-C16烯烃的形成可以通过交叉复分解反应或Julia-Kocienski烯化反应实现。
The formal synthesis of (+)-sorangicin A was completed by two independent routes. Both approaches feature a cross metathesis reaction to form the C29-C30 bond to arrive at the bicyclic ether/tetrahydropyran fragment. Formation of the C15-C16 olefin to unite the dihydropyran fragment with the rest of the molecule was achieved by either a cross metathesis reaction or a Julia-Kocienski olefination.
