Application

  • Synthesis and Anti-Oomycete Mechanism: Research focused on the synthesis of sulfonate derivatives of Ethyl Maltol, incorporating 2-Ethyl-3-hydroxy-4H-pyran-4-one, and their application in combating oomycete pathogens, providing insights into the preliminary mechanisms that enhance agricultural productivity and disease management (Xing et al., 2022).
  • Redox Activity in Co(III) Complexes: A study examined the effects of replacing traditional tripodal donors with two 2N chelators in Co(III) complexes containing maltolato (a derivative of 2-Ethyl-3-hydroxy-4H-pyran-4-one) on their redox behavior and cytotoxic activity, which is crucial for the development of novel therapeutic agents (Nagy et al., 2021).
  • Characterization of Wine Aroma Compounds: The role of 2-Ethyl-3-hydroxy-4H-pyran-4-one in the characterization of odor-active compounds in various cherry wines was explored using gas chromatography-mass spectrometry and olfactometry, highlighting its significance in enhancing sensory attributes and wine quality (Niu et al., 2011).

In this study, thirteen 3-hydroxy-6-methyl-2-substituted 4H-pyran-4-one derivatives were synthesized for the evaluation of their potential anticonvulsant activity. Mannich bases were prepared by the reaction of substituted piperazine derivatives with allomaltol and formaline. The structures of the synthesized compounds were confirmed
