Abstract

PURPOSE: To obtain the titled compound useful as an intermediate for agricultural chemical, perfume, and drug from a raw material prepared from naturally occurring substances extremely inexpensively by one step industrially advantageously, by rearranging furfuryl alcohol using a solvent comprising water as a main solvent.
CONSTITUTION: Furfuryl alcohol is rearranged in water alone or mixed solvent comprising water as a main solvent and a small amount of an organis solvent, and, if necessary, in the presence of a catalyst, in a pH of preferably 2W7, especially pH of 3W6.5 at preferably 20W160°C, to give extremely easily 4-hydroxy-2-cyclopentenone useful as an intermediate for prostagladins having smooth muscle contracting action, anti-inflammatory action, gastic juice suppressing action, and hypotensive action. Various kinks of metal salt, organic quaternary ammonium salt, surface active agent, alcohol, etc. may be used as the catalyst, and the addition of the catalyst improves the reaction rate and increases the conversion.
