BICYCLIC HETEROARYL INDOLE ANALOGUES USEFUL AS ROR GAMMA MODULATORS
-
Page/Page column 47; 48, (2015/06/25)
The present disclosure is directed to compounds of formula (I) and pharmaceutically acceptable salts thereof, wherein X, X1, M, R2, R3, R4, R5, m, n, and p are as defined herein, which are active as modulators of retinoid-related orphan receptor gamma t (RORγt). These compounds prevent, inhibit, or suppress the action of RORγt and are therefore useful in the treatment of RORγt mediated diseases, disorders, syndromes or conditions such as, e.g., pain, inflammation, COPD, asthma, rheumatoid arthritis, colitis, multiple sclerosis, neurodegenerative diseases and cancer.
Selective synthesis of indazoles and indoles via triazene-alkyne cyclization switched by different metals
Fang, Yan,Wang, Chengming,Su, Shengqin,Yu, Haizhu,Huang, Yong
, p. 1061 - 1071 (2014/02/14)
We described two orthogonal heterocycle syntheses, where an arene bearing both an alkyne and a triazene functionality underwent two distinct cyclization pathways mediated by different transition metals. Starting from the same substrates, a synthesis of 2H
Silver-catalyzed [3+2]-cycloaddition of benzynes with diazocarbonyl species via a postulated (1H-indazol-1-yl)silver intermediate

, p. 8948 - 8952,5 (2012/12/12)
We reported a new synthesis of 2-aryl-2H-indazoles via a silver-catalyzed [3+2]-cycloaddition of benzynes with diazocarbonyl reagents. We postulate that this transformation involves the generation of (1H-indazol-1-yl)silver to activate a subsequent arylation with the second benzyne.
The effect of substrate structure on the direction of cyclization of ortho-alkynylbenzene diazonium salts
Fedenok, Lidiya G.,Shvartsberg, Mark S.,Bashurova, Valentina S.,Bogdanchikov, George A.
body text, p. 67 - 69 (2010/03/01)
The cyclization of ortho-(arylethynyl)benzene diazonium salts (the Richter reaction) is studied. A reaction mechanism, which differs radically from that reported earlier is proposed and substantiated by experimental data and quantum-chemical calculations.
Design and synthesis of a new indazole library: direct conversion of?N-methoxy-N-methylamides (Weinreb amides) to 3-keto and 3-formylindazoles
Crestey, Fran?ois,Stiebing, Silvia,Legay, Rémi,Collot, Valérie,Rault, Sylvain
, p. 419 - 428 (2007/10/03)
Nucleophilic addition of Grignard or lithiated reagents on the new Weinreb amides 3 and 4 afforded efficiently the corresponding ketones and allowed the design and synthesis of a new indazole library. These 3-ketoindazoles were obtained by a direct and or
A novel synthesis of 3-substituted indazole derivatives
Welch,Hanau,Whalen
, p. 937 - 939 (2007/10/02)
The dianion prepared from 3-bromo-1H-indazole and alkyllithium bases reacts with a variety of electrophiles to give the corresponding 3-monosubstituted 1H-indazole derivatives in moderate yields. This procedure is more general and shorter than earlier methods.
