Research on furan acetal compounds

When 4-alkyl-2-(5-X-2-furyl)-1,3-dioxolanes are heated in the presence of tert-butyl peroxide the acetal ring is opened at the C-O 3–4 bond to give isomeric esters of 5-substituted furan-2-carboxylic acid. The structure of the product was confirmed by means of the UV and IR spectra, gas-liquid chromatography, and alternative synthesis.See 1] for communication VIII.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 10, pp. 1327–1329, October, 1976.
