The first total synthesis and absolute structure assignment of PD-116740 (2) was achieved by exploiting two key steps: 1) a thermal ring expansion of a benzocyclobutene derivative, and 2) pinacol cyclization of biaryl dialdehyde.
实现了PD-116740(2)的首次全合成和绝对构型指定,关键步骤包括:1)
苯并环丁烯衍
生物的热环扩张,以及2)双芳基二醛的pinacol环化。
