  Palladium-Catalyzed Direct C7-Arylation of Substituted Indazoles

  摘要：

  A novel direct C7-arylation of indazoles with iodoaryls is described using Pd(OAc)2 as catalyst, 1,10-phenanthroline as ligand, and K2CO3 as base in refluxing DMA. Direct C7-arylation of 3-substituted 1H-indazole containing an EWG on the arene ring gave the expected products in good isolated yields. In addition, a one-pot Suzuki-Miyaura/arylation procedure leading to C3,C7-diarylated indazoles has been developed.

  A method for the regioselective synthesis of 1-alkyl-1H-indazoles

  摘要：

  A method for the regioselective synthesis of 3-unsubstituted 1-alkyl-1H-indazoles, starting with 2-halobenzonitriles and N-alkylhydrazines, is described. The two-step reaction pathway proceeds through the intermediacy of 1-alkyl-3-amino-1H-indazoles followed by reductive deamination. (C) 2013 Elsevier Ltd. All rights reserved.

  The reactions of 1‐sulfonyl‐1H‐indazoles under basic conditions are discussed, and the direct N‐alkylation and Kemp elimination reactions of these compounds are reported. A series of 2‐(p‐tosylamino)benzonitriles and N‐alkyl indazoles were prepared in good yields. Moreover, the 2‐(p‐tosylamino)benzonitriles could be transformed into a diverse range of important derivatives in a one‐pot reaction. This

  讨论了在碱性条件下1-磺酰基-1 H-吲唑的反应，并报道了这些化合物的直接N-烷基化和Kemp消除反应。制备了一系列2-（对甲苯磺酰基氨基）苄腈和N-烷基吲唑，收率很高。此外，在一次反应中，2-（对甲苯磺酰基氨基）苯甲腈可转变为多种重要的衍生物。该方法已成功地应用于喹啉酮和隐烯酮的合成。喹啉酮是通过1-磺酰基-1 H-吲唑单锅反应制得的。

  The synthesis of a MET kinase inhibitor in an overall yield of 22% was achieved over eight steps starting with 3-hydroxybenzaldehyde, an improvement from the initial 12-step process with a 5.4% yield. Highlights of the process chemistry design and development are a Cu-catalyzed cyclization to form an important N1-methylindazole ring, a selective nitro reduction in the presence of an aryl bromide, a late-stage Suzuki cross-coupling, and a base-promoted Boc deprotection to form the desired drug candidate.
