Abstract

NEW MATERIAL:A cis-3. cis-5-octadienal shown by the formula I [Y is =O, or -(OR)2(R is 1W10C alkyl, 3W10C alkenyl, or form 2W3C methylene bond).
EXAMPLE: Cis-3.cis-5-octadienal dimethyl acetal.
USE: A lasting perfume, flavor, or modifier. or synthetic intermediate. Having improved perfume like fruits and lasting effects.
PROCESS: An acetal derivative of 3-butynal shown by the formula III is condensed with a 1-halogeno-butin shown by the formula IV(X is halogen) in the presence of an amine and a cuprous ion to give an acetal derivative of 3,5-octadienal shown by the formula II, which is subjected to catalystic hydrogenation in the presence of a catalystic hydrogenation catalyst to give a compound shown by the formula I where Y is -(OR)2.This compound is deacetalized, to give a compound shown by the formula I where Y is O.
