我们报告了“BN 融合”吲哚的第一个例子,并证明了这个新的非天然吲哚衍生物家族经历了与其有机类似物相同的区域选择性的亲电芳香取代 (EAS) 反应。竞争实验表明 Nt-Bu-BN-吲哚在 EAS 反应中比其碳质对应物更具亲核性。BN 吲哚和经典吲哚之间的 X 射线结构分析突出了键距的显着差异,尤其是与硼原子相关的键。
Palladium-catalysed N-annulation routes to indoles: the synthesis of indoles with sterically demanding N-substituents, including demethylasterriquinone A1
N-benzoyloxyamines, and norbornadiene. The Catellani and retro-Diels-Alder strategy was used in this domino process. o-Iodoaniline, with electron-donating and sterically hindered protecting groups, made the reaction selective toward o-C-H amination. On the basis of density functional theory calculations, the intramolecular Buchwald coupling of this reaction underwent a dearomatization and a 1,3-palladium migration
