Stabilizing Influence of Electron-Deficient Triazole Fragment on the Furan Heterocycle in Renewable Platform Chemicals

The effect of an aromatic triazole ring conjugated with a furan heterocycle on the stability of furan under various reaction conditions was studied, and a significant reduction in the degree of degradation of the electron-rich furan core and hydrolysis of the ester group under the action of a model acid and base in various organic solvents was shown. The lowest degree of degradation and hydrolysis of the triazole-substituted 2-furoic acid ester was achieved in dioxane, as well as in polar aprotic solvents (DMSO and DMF). It was shown that under the same conditions, a significant tarring and hydrolysis of the furan ester, which does not contain a conjugated triazole fragment, occurs.
