lactonization has been developed to construct the central spirolactone core of trigolutes with the requisite functional groups. A large number of analogues of trigolute B have been synthesized. Furthermore, the synthesis of both (±)-trigolute B and (±)-3-epi-trigolute B has been accomplished in 4–5 steps from easily accessible building blocks.
已经开发出一种简明的方法,该方法包括Pd或Ir催化的Tsuji-Trost烯丙基化和烯烃二羟基化/酸催化的内酯化的组合,以构建具有必要官能团的三甲酚的中央螺内酯核心。已经合成了大量三水甘油三酯的类似物。此外,(±)-Trigolute B和(±)-3-epi-trigolute B的合成已从易于获得的构建基块以4-5个步骤完成。
