New Compounds in the Reaction of Aromatic Amines and 5-Hydroxy-4-pyrone-2-carboxylate. The Influence of a Methoxy Group

Unlike most of other aromatic amines, 4-methoxyaniline with methyl comenate (1) in the mixture of acetic acid and methanol (1:1) gave the unexpected products with azomethyne moiety. The structures of new compounds were determined from their characteristic spectroscopic behaviour and were confirmed by X-ray crystallographic measurements.
