validation of 3-aminobenzyne precursors induced by C-(sp2)-to-N 1,3-aza-Brook rearrangement have been achieved, allowing access to diverse aniline derivatives. Through crossover experiments, we demonstrated the intramolecular mechanism of 1,3-C-to-N silyl transfer. To gain insight into the regioselectivity observed in the reactions, we performed density functional theory calculations. Finally, the method
已经实现了由 C-(sp 2 )-N 1,3-氮杂-布鲁克重排诱导的 3-氨基苄前体的设计、合成和验证,从而可以获得多种苯胺衍生物。通过交叉实验,我们展示了 1,3-C-to-N 甲硅烷基转移的分子内机制。为了深入了解反应中观察到的区域选择性,我们进行了密度泛函理论计算。最后,将该方法应用于以 30% 的总产率以五个线性步骤合成木聚糖 A。
