The synthesis of hemi-(hydro)-pyrenophorinketale (I) starting from the 5-methyl-2-furfural (III) via the substituted γ-valerolactone (X) is reported.The lactone (XV), α,β-unsaturated analogous of (X), by basic hydrolysis and esterification affords the same ketoester (XII) obtained from (X) by oxidation of the corresponding open hydroxiester.
