Herein, we report a synthetic method to access a range of highly substituted indoles via the B(C6F5)3-catalyzed transfer of 2° alkyl groups from amines. The transition-metal-free catalytic approach has been demonstrated across a broad range of indoles and amine 2° alkyl donors, including various substituents on both reacting components, to access useful C(3)-alkylated indole products. The alkyl transfer process can be performed using Schlenk line techniques in combination with commercially available B(C6F5)3·nH2O and solvents, which obviates the requirement for specialized equipment (e.g., glovebox).

通过 B(C6F5)3 催化的仲烷基转移获得高度取代的吲哚



在此,我们报告了一种通过 B(C 6 F 5 ) 3催化的胺的 2° 烷基转移获得一系列高度取代的吲哚的合成方法。无过渡金属的催化方法已在广泛的吲哚和胺 2° 烷基供体(包括两种反应组分上的各种取代基)中得到证明,以获得有用的 C(3)-烷基化吲哚产物。烷基转移过程可以使用Schlenk线技术结合市售的B(C 6 F 5 ) 3 · n H 2 O和溶剂来进行,这消除了对专用设备(例如手套箱)的需要。
