Hydrolysis of allyl carbinol oxides in aqueous HClO4 gave the corresponding 1,2,4-triols. On heating in the same reaction medium, they underwent cyclization into 3-hydroxytetrahydrofurans. The method is restricted to substrates that can generate stable carbocations via elimination of the hydroxy group from position 4 in intermediate 1,2,4-triols.
