Uses

Tiglic aldehyde was used in the concise total synthesis of 7-demethylpiericidin A1. It was used as starting reagent during the synthesis of:

alkyl-branched tetraene hydrocarbons, pheromone component for dried fruit beetle
E,E-2,4-dimethyl-2,4-hexa dienal, volatile constituents of the defensive secretions of Leiobunum nigripalpi
4-methyl-2,4-hexadiene-1-ol
