Application

Quinuclidine can be used as a catalyst:
  • In the Baylis-Hillman reaction of aldehydes with methyl acrylate.
  • For the epimerization of α-methylglucose to α-methylallose.
It can also be used as a reactant to synthesize 5-[4-[2-(acetyloxy)ethyl]-1-piperidinyl]-2-pyridinecarbonitrile by reacting with 5-bromo-2-pyridinecarbonitrile in the presence of potassium acetate.
