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
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。
