3-Quinuclidinone is a bicyclic organic compounds with chemical formula . Its basicity is indicated by the pKa of the conjugate acid, which is 7.2. In contrast quinuclidine is about 100x more basic.
Its hydrochloride salt can be synthesized by a Dieckman condensation: It is a precursor to quinuclidine.
Organic reduction of 3-quinuclidone gives the compound quinuclidine, structurally related to DABCO, which has one additional bridgehead nitrogen atom.
