Copper-diamine-catalyzed N-arylation of pyrroles, pyrazoles, indazoles, imidazoles, and triazoles. [Erratum to document cited in CA141:207140] was written by Antilla, Jon C.;Baskin, Jeremy M.;Barder, Timothy E.;Buchwald, Stephen L.. And the article was included in Journal of Organic Chemistry in 2004.Reference of 741717-60-2 The following contents are mentioned in the article:
On page 5578, an important reference describing the copper-catalyzed N-arylation of pyrazoles was left out of the manuscript: Cristau, H.-J., Cellier, P. P.; Spindler, J.-F.; Taillefer, M. Eur. J. Organic Chem. 2004, 695-709. This study involved multiple reactions and reactants, such as Ethyl 1-(pyridin-3-yl)-1H-pyrazole-4-carboxylate (cas: 741717-60-2Reference of 741717-60-2).
Ethyl 1-(pyridin-3-yl)-1H-pyrazole-4-carboxylate (cas: 741717-60-2) belongs to pyrazole derivatives. An alternative way to synthesize multisubstituted pyrazoles is the Csingle bondH arylation of simple pyrazoles. Pyrazole rings have been used as core components of several leading non-steroidal anti-inflammatory drugs (NSAIDs) and antihypertensive drugs. It has also been found to be useful as a bifunctional ligand for metal catalysis.Reference of 741717-60-2
