Reaction Steps
10 g of 4-oxo-3-oximino-2,5-dimethyl-tetrahydrofuran and 50 ml of 10% strength H2SO4 are heated at 80° C and the hydrolysis is followed by thin layer chromatography. The oxime has been converted after 3 hours. In its place, 4-oxo-3-hydroxy-2,5-dimethyl-4,5-dihydrofuran has been formed, as established by isolating the product and comparing the chromatographic and spectroscopic data with those of a comparative substance.
