As hypoxia is an important factor to limit chemotherapeutic efficacy in tumors, we herein report three ruthenium(II)-arene complexes containing a hypoxia inducible factor-1α inhibitor (YC-1), which endow the organometallic complexes with potential for hyp
Suzuki-type cross-coupling reaction of 3-iodoindazoles with aryl boronic acids: A general and flexible route to 3-arylindazoles

, p. 6917 - 6922 (1999)
This paper describes a Suzuki Type cross coupling reaction of 3- iodoindazoles with aryl and heteroaryl boronic acids as a general route to 3- arylindazoles. The coupling reaction is illustrated by the preparation of new aryl- or heteroarylindazoles 7. Scope and limitation of the method are outlined. The coupling reaction works best on a 1-substituted indazole nucleus. The usefulness of the reaction is illustrated by a short practical synthesis of YC-1, a pharmacological agent potentially useful for the treatment of cardiovascular diseases or erectile dysfunction.
Palladium-Catalyzed C-H/C-H Cross-Coupling by Mechanochemistry: Direct Alkenylation and Heteroarylation of N1-Protected 1 H-Indazoles

C3-alkenylated and C3-(hetero)arylated 1H-indazoles are privileged structural motifs in numerous pharmaceuticals. Direct C3-alkenylation and C3-(hetero)arylation of 1H-indazoles have been significantly challenging because of the inert nature of this carbon center. Herein, we present an efficient mechanochemical strategy for palladium-catalyzed C-H/C-H cross-coupling to construct C3-alkenylated and C3-heteroarylated 1H-indazoles using low-cost copper oxidants with satisfactory product yields and broad functional group tolerance. The robustness of the developed protocols was further demonstrated by the unprecedented total mechanosynthesis of the intermediate of PLK4 inhibitor CFI-400945 and HIF-1α inhibitor YC-1.

Tang, Meng,Kong, Yuanfang,Chu, Bingjie,Feng, Dan
, p. 926 - 939 (2016/04/05)
An efficient synthesis of indazoles from readily accessible E/Z mixtures of o-haloaryl N-tosylhydrazones has been developed. The thermo-induced isomerization of N-tosylhydrazones is discussed. A series of valuable indazole derivatives are prepared in good yields, and the method has been successfully applied to the synthesis of the bioactive compounds, lonidamine, AF-2785, axitinib, YC-1 and YD-3.

1-Benzyl-3-(substituted aryl)-5-methylfuro[3,2-c]pyrazole (YC-1) is a well-known synthetic compound with various satisfactory pharmacological activities, such as the activation of soluble guanylate cyclase (sGC) and the inhibition of hypoxia-induced facto
Pd- and Cu-catalyzed C-H arylation of indazoles
Hattori, Keika,Yamaguchi, Kazuya,Yamaguchi, Junichiro,Itami, Kenichiro
, p. 7605 - 7612 (2012/09/07)
The palladium- and copper-catalyzed C-H arylation reactions of 1H- and 2H-indazoles with haloarenes are described. A PdCl2/phen/Ag 2CO3/K3PO4 catalytic system is effective for the C-H arylation of 1H- and 2H-indazoles with haloarenes, whereas a less expensive CuI/phen/LiOt-Bu catalytic system is applicable to the C-H coupling of substituted 2H-indazoles and iodoarenes. The utility of newly developed catalyst was demonstrated in the rapid synthesis of YC-1 (an antitumor agent) and YD-3 (platelet anti-aggregating agent). These new reactions represent important direct functionalization tools of indazoles, well-known bioisosteres of pharmaceutically important indole core.
