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.

Oxidative cleavage of arachidonate (C(20)) and linoleate (C(18)) phospholipids generates truncated C(8) or C(12) gamma-hydroxyalkenal phospholipids as well as C(5) or C(9) carboxyalkanoate phospholipids, which are abundant in atherosclerotic plaques. The gamma-hydroxyalkenals promote foam cell formation by scavenger receptor CD36-mediated

A general approach for the synthesis of 3,5-diarylcyclopentenones was developed. Key aspects of this approach are the intramolecular Friedel-Crafts-type cyclization of vinyl chlorides and subsequent Pd-catalyzed cross-coupling reactions. The requisite vinyl chloride-bearing arylacetic acid precursors are readily available by straightforward
