Total synthesis of Hirsutellone B has been achieved by a convergent synthetic strategy. This synthesis features direct construction of the highly strained 13-membered macrocycle of Hirsutellone B utilizing the Ullmann-type reaction. To the best of our knowledge, this is the first application of macrocyclization utilizing an intramolecular Ullmann-type reaction between an aliphatic alcohol and aryl
通过收敛的合成策略已经实现了Hirsutellone B的全合成。该合成的特征是利用Ullmann型反应直接构建Hirsutellone B的高应变13元大环。据我们所知,这是利用脂族醇与芳基卤化物之间的分子内乌尔曼型反应进行大环化的首次应用。
