Application

1-Penten-3-one can be used as a reactant to synthesize:
  • Conjugated dienes via palladium-catalyzed Heck reaction with vinyl bromides.
  • β-Amino carbonyl derivatives via solvent-free aza-Michael addition reaction with aromatic amines in the presence of ionic liquid catalyst.
  • α-Exo-methylene group bearing β-amino carbonyl compounds via ion-supported triphenylphosphine catalyzed aza‐Morita‐Baylis-Hillman reaction with N-tosyl arylimines.
Reagent for annulation.

alpha,beta-Unsaturated ketones are bifunctional compounds which form promutagenic 1,N(2)-propanodeoxyguanosine adducts like carcinogenic alpha,beta-unsaturated aldehydes and are mutagenic and genotoxic like these aldehydes. They are important industrial chemicals, are found in our environment and are widespread in our food. We investigated
