General description

1-undecene (or α-undecene) is an organic compound, which belongs to the class of unsaturated aliphatic hydrocarbons. It is a hydrophobic molecule found in the essential oil of Farfugium japonicum and some mushroom species.

Application

1-undecene is an alkene that can be used as a reactant:
  • In the Pd-catalyzed aerobic oxidative amination reaction with nitrogen nucleophiles to produce useful amine analogs.
  • To prepare a key intermediate in the total synthesis of (+)-deoxoprosopinine.
