  摘要：

  我们先前强调了6,5,6-融合三环类4-氨基喹唑啉作为激酶抑制剂在微摩尔到纳摩尔范围内的IC50值的兴趣。为了生成化学库，使用甲酰胺介导的氰基胺前体的环化反应在微波辐射下进行，采用环保的方法。为了更深入地探索这种三环骨架的药理学兴趣，中心的五元环，即噻吩或呋喃，被替换为吡咯，以制备受到harmine启发的9H-嘧啶并[5,4-b]-和[4,5-b]吲哚-4-胺衍生物。最终产品的抑制效力被测定对四种蛋白激酶（CDK5/p25、CK1δ/ε、GSK3α/β和DYRK1A）。结果，我们已经确定了有前途的化合物，靶向CK1δ/ε和DYRK1A，显示微摩尔和亚微摩尔的IC50值。

  Microwave assisted synthesis of 3-aminoindole-2-carbonitriles from anthranilonitriles via N-unprotected 2-(cyanomethylamino)benzonitriles

  摘要：

  Anthranilonitrile 3a, 4,5-dimethoxyanthranilonitrile 3b and 5-nitroanthranilonitrile 3c, react with paraformaldehyde, KCN and ZnCl2 in acetic acid under acid catalysis (H2SO4) in a sealed tube at ca. 55 degrees C to give the corresponding 2-(cyanomethylamino)benzonitriles 4a-c in 96, 86 and 57% yields, respectively. Thorpe-Ziegler cyclisation of the N-unprotected 2-(cyanomethylamino)benzonitriles 4a-c with K2CO3 in EtOH at elevated temperatures and pressures using either microwave heating or conventional heating in a sealed tube gives 3-amino, 3-amino-5,6-dimethoxy, and 3-amino-5-nitro-indole-2-carbonitriles 2a-c in moderate to good yields.

  The condensation of 2-aminoindole-3-carbonitriles and their 3-aminoindole-2-carbonitrile isomers with various DMF-dialkoxyacetals was investigated under microwaves. The appearance of reactive and versatile alkoxyiminium species allowed convenient access to indole precursors of building blocks with potential biological activity. The experimental results have been rationalised using DFT calculations of theoretical descriptors based on the electrostatic potential.

• Detosylation of 3-amino-1-tosylindole-2-carbonitriles using DBU and thiophenol

  日期：2010.4

  Attempted detosylation of the 3-amino-1-(p-tosylamino)indole-2-carbonitriles 4a-c using either K2CO3 in EtOH or DBU in PhH at reflux gives unexpectedly the 3-(N-p-tosylamino)indole-2-carbonitriles 5a-c, respectively in high yields. Nevertheless, treatment of 1-(p-tosylamino)indoles 4a-c with thiophenol and DBU in PhH at reflux gives the detosylated 3-aminoindole-2-carbonitriles 5a-c. Reaction mechanisms supporting the tosyl migration (4 -> 5) and the reductive detosylation (4 -> 2) are proposed. All new compounds are fully characterised. (C) 2010 Elsevier Ltd.
