ABSTRACT:
The present invention provides a cis-configurational unsaturated ester represented by the formula (1) ##STR1## (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) ##STR2## (where n is defined as above) with a Grignard reagent represented by the formula (3a)
