De Novo Synthesis of Benzannelated Heterocycles
Feierfeil, Johannes,Magauer, Thomas
, p. 1455 - 1458 (2017/12/28)
Benzannelated heterocycles such as indoles and indazoles are prominent structural motifs found in natural products, pharmaceuticals and agrochemicals. For their synthesis, chemists traditionally either functionalize commercially available heterocycles or resort to transformations that make use of benzene-derived building blocks. Here, we report a powerful cascade reaction that enables the de novo construction of variously substituted indoles, indazoles, benzofurans and benzothiophenes from readily available bicyclo[3.1.0]hexan-2-ones. The transformation can be conducted under mild, non-anhydrous conditions. For the synthesis of indoles, mechanistic studies revealed that the electrocyclic ring-opening of the bicyclic ring-system and aromatization precedes the 3,3-sigmatropic rearrangement.
Synthesis of 3-indazolecarboxylic esters and amides via Pd-catalyzed carbonylation of 3-iodoindazoles
Buchstaller, Hans-Peter,Wilkinson, Kai,Burek, Kasimir,Nisar, Yasmin

A straightforward and effective procedure for the preparation of 1H-indazole-3-carboxylic acid esters and amides was developed. A series of functionalized 3-iodoindazoles were subjected to Pd-catalyzed carbonylations in the presence of methanol or amines,

Indazole compounds that modulate and/or inhibit the ophthalmic diseases and the activity of certain protein kinases are described. These compounds and pharmaceutical compositions containing them are capable of mediating tyrosine kinase signal transduction and thereby modulate and/or inhibit unwanted cell proliferation. The invention is also directed to the therapeutic or prophylactic use of pharmaceutical compositions containing such compounds, and to methods of treating ophthalmic diseases and cancer and other disease states associated with unwanted angiogenesis and/or cellular proliferation, such as diabetic retinopathy, neovascular glaucoma,rheumatoid arthritis, and psoriasis, by administering effective amounts of such compounds.
