  N-arylation of 3-alkoxypyrazoles, the case of the pyridines

  摘要：

  In the course of a research program focused on the preparation of libraries of new chemical entities derived from 3-alkoxypyrazoles, we studied their N-pyridylation using 2, 3 or 4-bromopyridines This was achieved using Cristau and Taillefer copper-catalyzed arylation method and mostly led to the 3-alkoxy-1H-pyrazol-1-yl pyridine isomer along with lesser amount of the alternative 5-alkoxy-1H-pyrazol-1-yl pyridine The structures of these isomers were often established via their chemical tansformations and sometimes recourse to unambiguous synthetic routes for comparison purposes The alternative use of 2-fluoropyridine-based arylation was also investigated and lifted some of the limitations encountered in the course of this study (C) 2010 Elsevier Ltd All rights reserved

  Our current interest in the design of original chemical libraries featuring a pyrazole nucleus led us to focus on the chemistry of the 3-alkoxy-5-methylpyrazoles we have recently made readily available. With in mind the preparation of an array of the less accessible 1-arylpyrazol-3-ones, the present report describes the respective nitrogen's reactivity of various 3-alkoxypyrazoles toward arylation reaction, using arylboronic acids, as well as alkylation reactions using methyl iodide or benzylbromide. The structure assignments of the isomers obtained were achieved using long distance N-15-H-1 NMR correlation measurements or by the recourse to unambiguous synthetic pathways. (c) 2009 Elsevier Ltd.
