  Nitrogen's reactivity of various 3-alkoxypyrazoles

  摘要：

  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.
