CIS-4-HEPTENAL Usage And Synthesis

Description

cis-4-Heptenal has an odor reminiscent of heptaldehyde. It is suggestive of fried fats on dilution. It is used to impart a fried, buttery flavor. It is prepared from Hemiptera insects (trans-form); from pen-ten-l-en-3-ol converted to the corresponding vinyl ether which undergoes a Claisen rearrangement to 4-heptenal (transform).

Chemical Properties

Chemical Properties

clear colorless to light yellow liquid

Chemical Properties

(Z)-4-Heptenal is a widespread volatile trace constituent of food flavors. It is a colorless, oily liquidwith a powerful, fatty, somewhat fishy, and, in high dilution, creamy odor. It can be prepared by several ways, for example, by starting from (Z)-3-hexenol.
(Z)-4-Heptenal is used in cream, butter, and fat flavors.

Occurrence

Reported found as a constitutent in butterfat, microbial fermented tea and black Hemiptera bugs

Preparation

From Hemiptera bugs (trans-form); from penten-1-en-3-ol converted to the corresponding vinyl ether, which undergoes a Claisen rearrangement to 4-heptenal (trans-form).
