Résumé:
The synthesis of new 2-pyrone-based hydrazones has been prepared
by the coupling of 6-methyl-2H-furo[3,2-c]pyran-3,4-dione with
diazonium salts, obtained by diazotization of aniline derivatives. The
structure of all compounds was established by spectroscopic methods,
and the structure of the more stable conformer was theoretically
confirmed by the potential energy profile analysis. The prepared
2-pyrone-based hydrazone dyes were acetylated and both groups of
compounds showed moderate to good radical scavenging activity.
