The reaction of alpha-phenyl-beta-formylacrylic derivatives with various amidines (benzamidine, acetamidine) and heterocyclic amidines (2-aminopyridines, 3-aminopyridazines), yields alpha-substituted imidazolylphenylacetic acids and imidazo[1,2-x] azines bearing a phenylacetic acid residue in position 3. Some mechanistic aspects of the cyclocondensation reaction will be discussed.

Abstract
The reaction of alpha-phenyl-beta-formylacrylic derivatives with various amidines (benzamidine, acetamidine) and heterocyclic amidines (2-aminopyridines, 3-aminopyridazines), yields alpha-substituted imidazolylphenylacetic acids and imidazo[1,2-x] azines bearing a phenylacetic acid residue in position 3. Some mechanistic aspects of the cyclocondensation reaction will be discussed.File in questo prodotto:
