Application

Tiglic aldehyde was used in the concise total synthesis of 7-demethylpiericidin A1[1]. It was used as starting reagent during the synthesis of:
  • alkyl-branched tetraene hydrocarbons, pheromone component for dried fruit beetle[2]
  • E,E-2,4-dimethyl-2,4-hexa dienal, volatile constituents of the defensive secretions of Leiobunum nigripalpi[3]
  • 4-methyl-2,4-hexadiene-1-ol[4]
