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).
