Abstract

PURPOSE: To prepare the titled compound useful as a high-grade perfume for cosmetics and soaps, in high yield and purity, at a low cost, economically, in an industrial scale, by reducing an easily available 4-hydroxycyclopentenone derivtive as the starting material.
CONSTITUTION: A 4-hydroxycyclopentenone derivative of formula I is used as a raw material, and reduced in the presence of a Lindlar catalyst such as palladium- calcium carbonate, etc. at 0W200°C to obtain the compound of formula II. The compound of formula I is obtained by the isomerizaton of a cyclopentenone derivative of formula IV prepared by the rearragement of a furan carbinol derivative of formula III in a solvent such as water, dioxane, etc. in the presence or absence of a catalyst.
