Abstract
NEW MATERIAL:To ether derivative of cyclopentenone compound of formulaI (R1 is H, alkyl, or alkenyl; R2 is R1, cycloalkyl, aryl, aralkyl, ω-cyanohexyl, or ω-t-butoxycarbonyl-hexyl; A is OH residue of a compound having OH group, provided that A is not methyl).
EXAMPLE: 2-ethyl-4-ethoxy-2-cyclopentenone.
USE: Pesticide or its intermediate. Also useful as perfumery, pharmaceuticals or their intermediates.
PROCESS: The compound of formulaIcan be prepared by reacting the 3-hydroxy- 4-cyclopentenone compound of formula II with an OH-containing compound (e.g. ethanol, isopropyl alcohol, etc.) in the presence of a catalyst such as toluenesulfonic acid at 0W200°C.
