Hydrogenation of furfuryl alcohol can proceed to give hydroxymethyl derivative of tetrahydrofuran and 1,5-pentanediol. The etherification reaction of furfuryl alcohol with alkyl or aryl halide (e.g. benzyl chloride) in the liquid-liquid-liquid triphase system with the help of a phase transfer catalyst also reported.

[1] [2] This discovery occurred when Piancatelli was studying heterocyclic steroids and their reactive abilities in an acidic environment. As this rearrangement has continued to be studied, it has become a commonly used rearrangement in natural product synthesis because of the ability to create 4-hydroxy-5-substitutedcyclopent-2-enones.
