A simple and efficient one-potsynthesis of substituted indolo[1,2-a]quinolines under transition-metal-free conditions has been developed. When 2-fluorobenzaldehyde was treated with substituted 2-methylindoles in the presence of Cs2CO3, the desired products were typically obtained in good to excellent yields. This reaction sequence involves a nucleophilic aromatic substitution and a Knoevenagel condensation
已经开发了一种在无过渡金属条件下简单高效的一锅合成取代吲哚[1,2- a ]喹啉的方法。当在Cs 2 CO 3存在下用取代的2-甲基吲哚处理2-氟苯甲醛时,通常以良好或优异的产率获得所需产物。该反应序列涉及亲核芳族取代和Knoevenagel缩合反应。我们的机理研究表明,第一步中两个反应都可能以分子间反应的形式进行。

Directcyanation of indole derivatives has been achieved with nontoxic K4[Fe(CN)6] as cyanating agent through Pd-catalyzed C−Hbondactivation.
The present invention relates to compounds useful as promoters of the SMN2 gene. The invention also provides pharmaceutically acceptable compositions comprising said compounds and methods of using the compositions in the treatment of Spinal Muscular Atrophy.
Indoles undergo smooth cyanation with CuCN in the presence of 20 mol% Pd(OAc)(2) and 40 mol% CuBr2 in DMF to produce a wide range of the corresponding 3-cyanoindoles in good yields with high regioselectivity. (C) 2010 Elsevier Ltd. All rights reserved.
