Description:

Hydroxypyrone (Synonym: 2-Hydroxypyrone) is a heterocyclic organic molecule containing an oxygen-functionalized unsaturated pyrone ring system. Its distinct electron-rich framework and conjugated keto-enol tautomerism impart exceptional reactivity for cycloaddition reactions, organocatalytic functionalization, and coordination chemistry.
