Abstract
There are provided novel jasmonic acid compounds of the following general formula (1) wherein R is a group selected from the group consisting of an alkenyl group of 3 to 6 carbon atoms, an alkynyl group of 3 to 6 carbon atoms, and a hydroxyalkyl group of 2 or 3 carbon atoms, and X is CH2—CH2 or CH═CH. These novel jasmonic acid compounds are prepared by an ester exchange reaction between a corresponding jasmonic acid methyl ester and an alcohol.
Claims2
A jasmonic acid compound of the following general formula (1)
- wherein R is a group selected from the group consisting of an alkenyl group of 3 to 6 carbon atoms, an alkynyl group of 3 to 6 carbon atoms, and a hydroxyalkyl group of 2 or 3 carbon atoms, and X is CH2—CH2 or CH═CH.
A process for preparing a jasmonic acid compound of the following general formula (1)
- wherein R is a group selected from the group consisting of an alkenyl group of 3 to 6 carbon atoms, an alkynyl group of 3 to 6 carbon atoms, and a hydroxyalkyl group of 2 or 3 carbon atoms, and X is CH2—CH2 or CH═CH, which comprises effecting an ester exchange reaction by allowing an alcohol of the following general formula (3)
- R—OH (3)
- wherein R is a group selected from the group consisting of an alkenyl group of 3 to 6 carbon atoms, an alkynyl group of 3 to 6 carbon atoms, and a hydroxyalkyl group of 2 or 3 carbon atoms, to act on a jasmonic acid methyl ester of the following general formula (2)
- wherein X is CH2—CH2 or CH═CH.
