Abstract

Abstract Perfume or aroma compsns. contain dodeca-4,8-diene-1, 12-dialdehyde having formula OHC-(CH2)2-CH=CH-(CH2)2-CH=CH-(CH2)2-CHO. This cpds. is normally used in the form of a mixt. of its stereoisomers; the 4-trans-8-trans and 4-vis-8-cis stereoisomers being new cpds. These cpds. can be produced by ozonolysis of cyclododeca-1,5,9-triene and reduction of the resulting ozonide. These cpds. can be used for developing or modifying aroma of the flowing scenting agents of the aldehyde series.
