Abstract

PURPOSE: 3-Alkyl-2,3-epoxycyclopentanone is brought into contact with a strong acid type ion-exchange resin in the presence of a non-aquous solvent to produce readily title compound useful for a flavor even with use of a large amount of an expensive catalyst.
CONSTITUTION: 3-Alkyl-2,3-epoxycyclopentanone as 3-methyl-2,3-epoxycyclopentanone is brought into contact with a strong acid type ion-chchange resin as Amberlite 15 made by Rohm & Haas Co. in the presence of an aqueous solvent as acetone or tetrahydrofuran at 0 - 120, preferably 20 - 80°C to produce 2-hydroxy-3-alkyl- 2-cyclopentenone.
