CIS-4-HEPTENAL Usage And Synthesis
  • Descriptioncis-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).
