  The Synthesis of Some Derivatives Based on the 4-Benzyl-1H-pyrazole-3,5-diamine Core

  摘要：

  The three-step synthesis of 4-benzyl-1H-pyrazole-3,5-diamines 2 from commercially available aldehydes 3 is given. The Knoevenagel condensation was utilized to assemble the initial carbon framework, resulting in the benzylidenemalononitriles 4 which were directly transformed by the reduction of the electron deficient C=C bond to benzylmalononitriles 5. Subsequent cycloaddition of hydrazine with 5 afforded the desired pyrazoles 2. Due to the high similarity with 4-arylazo-1H-pyrazole-3,5-diamines, the biological activities of the 4-benzyl-1H-pyrazole-3,5-diamines 2 were evaluated while focusing on the inhibition of cyclin-dependent kinases (CDKs), but no significant results were obtained.

• Monosubstituted Malononitriles: Efficient One-Pot Reductive Alkylations of Malononitrile with Aromatic Aldehydes

  been developed for the reductive alkylation of malononitrile with aromatic aldehydes. This new procedure has vastly improved the yield and efficiency of the process, and increased the scope of the aromatic aldehydes. Incorporating water as the catalyst in ethanol for the condensation step allows stoichiometric amounts of malononitrile and aldehyde to be employed. The reduction step takes place quickly

  已经开发了一种强大的新一锅法，用于丙二腈与芳香醛的还原烷基化。这种新工艺极大地提高了工艺的产率和效率，并扩大了芳香醛的范围。在缩合步骤的乙醇中加入水作为催化剂允许使用化学计量的丙二腈和醛。还原步骤用硼氢化钠快速有效地进行，通过过滤或萃取得到单取代的丙二腈。2-喹啉甲醛的产物迅速重排为新的中氮茚，而单取代衍生物的烷基化提供了不重排的不对称二取代丙二腈。
• Tris(trimethylsilyl)silane-mediated Reductive Decyanation and Cyano Transfer Reactions of Malononitriles

  日期：2018.4.5

  Reductive decyanation reactions of malononitriles were achieved with tris(trimethylsilyl)silane as a radical mediator. The reaction proceeds via a radical chain mechanism involving a silyl radical addition to the malononitrile to form an imidoyl radical followed by α-cleavage to give a silyl isocyanide and an α-cyano radical. The reaction of a 3-butenyl-substituted malononitrile afforded a decyano/cyanosilylation

  丙二腈的还原脱氰反应是用三（三甲基甲硅烷基）硅烷作为自由基介体实现的。该反应通过自由基链机制进行，包括甲硅烷基自由基加成到丙二腈以形成亚胺酰基自由基，然后α-裂解得到甲硅烷基异氰化物和α-氰基自由基。3-丁烯基取代的丙二腈的反应通过1,4-氰基转移以良好的产率提供了脱氰基/氰基硅烷化产物。
