  Divergent cyclisations of 2-(5-amino-4-carbamoyl-1H-pyrazol-3-yl)acetic acids with formyl and acetyl electrophiles

  摘要：

  The reaction of 2-(5-amino-4-carbamoyl-1-methyl-1H-pyrazol-3-yl) acetic acid and triethylorthoformate did not give the expected dihydropyrazolo[4,3-c]pyridin-4-one product as described in literature, but formed an alternative cyclic imide product, fully characterised by NMR and X-ray crystallography. This mode of reaction was shown to be general to other 1-substituted-2-(5-amino-4-carbamoyl-1H- pyrazol-3-yl) acetic acids. The outcome of the cyclisation was highly sensitive both to the nature of the reagents used and also to the acidity of the reaction medium, such that a number of interesting bicyclic heterocycles could be produced in a controlled fashion from the single starting material. The major tautomeric forms of the bicyclic products in solution were found to vary according to their substitution pattern. (c) 2007 Elsevier Ltd. All rights reserved.
