Quinuclidine is an organic compound and a bicyclic amine and used as a catalyst and a chemical building block. It is a strong base with pKa of the conjugate acid of 11.0. This is due to greater availability of the nitrogen lone pair. It can be prepared by reduction of quinuclidone.
Quinuclidine is found as a structural component of some biomolecules including quinine.
