Cis-configurational unsaturated ester, process for producing the same, and fragrance composition containing the same |
| abstract |
The present invention provides a cis-configurational unsaturated ester represented by the formula (1) (where R is a methyl group or a phenyl group, and n is 1 or 2) and also provides a fragrance composition containing the cis-configurational unsaturated ester in an effective amount. The cis-configurational unsaturated ester represented by the formula (1) can be produced by reacting a cyclic vinyl ether represented by the formula (2a) (where n is defined as above) with a Grignard reagent represented by the formula (3a)RMgX(3a)(where R is defined as above, and X is a chlorine atom, a bromine atom or an iodine atom) in the presence of a triarylphosphine and not more than 0.05 mol of a nickel compound per one mole of the cyclic vinyl ether represented by the formula (2a) to give a cis-configurational unsaturated alcohol represented by the formula (4a) (where n and R are defined as above); and subjecting this cis-configurational unsaturated alcohol to acylation with acetic acid or a derivative thereof to give the cis-configurational unsaturated esters represented by the formula (1). |
