Application

2-Ethylacrolein can be used as a promoter to synthesize 2-alkylchroman-4-ones via rhodium-catalyzed annulation reaction of 1,3-dienes with salicylaldehydes or 2-hydroxybenzyl alcohols.
It can also be used as a reactant:
  • In the total synthesis of (±)-tabersonine, an indole alkaloid of the Aspidosperma family.
  • To prepare 2-ethylbicyclo[2.2.1]hept-5-ene-2-carboxaldehyde via enantioselective Diels-Alder reaction with cyclopentadiene in the presence of chiral Lewis acid catalyst.
  • To synthesize diethyl 5-ethyl-2,3-pyridinedicarboxylate by reacting with 2-chloro-3-oxo-succinic acid diethyl ester using ammonium acetate as a catalyst.
