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.

The organocatalyzed addition of several malonates to 1,4-benzoquinones affords benzofuranones bearing a quaternary stereocenter with good enantioselectivity. This reaction is an intramolecular desymmetrization since it proceeds through the formation of an arylated achiral malonate that cyclizes to give the reaction

[reaction: see text] The ionic liquid-bound quinuclidine catalyzed Baylis-Hillman reactions were investigated. The IL-supported catalyst showed equally good catalytic activity as compared with its nonimmobilized counterpart. The corresponding Baylis-Hillman adducts were obtained in moderate to high yields in all the

The reactivity of a variety of quinuclidine-based catalysts in the Baylis-Hillman reaction has been examined, and a straightforward correlation between the basicity of the base and reactivity has been established, without exception. The following order of reactivity was established with
