Spiroazetidine–piperidine bromoindane as a key modular template to access a variety of compounds via C–C and C–N bond-forming reactions
摘要:
In the context of our ghrelin inverse agonist program, a functionalized bromoindane 3 provided a versatile intermediate for structure-activity relationship studies. After developing operationally simple cross-coupling reactions, a broad spectrum of chemical space was successfully explored. Optimization of a one-pot borylation/Suzuki sequence provided the desired products in high yield with low loading of the palladium catalyst. High yields of N-linked heterocyclic analogues were obtained through palladium catalyzed C-N bond formation. In addition, carboxylation of the bromoindane provided an indane carboxylic acid for further diversification. (C) 2012 Elsevier Ltd. All rights reserved.
The present invention provides compounds, compositions thereof, and methods of using the same for the inhibition of TYK2, and the treatment of TYK2-mediated disorders.
series of tetradentate cyclometalated platinum(II) complexes (Pt 1, Pt 2, and Pt 3) based on 2-phenylbenzimidazole-containing ligands have been prepared. Their photophysical properties were investigated by absorption and emission spectroscopy as well as density functional theory calculations. Due to the robustness of their coordination frameworks, these Pt(II) complexes exhibited excellent thermal stabilities
