Experimental and theoretical study on the substitution reactions of aryl 2,4-dinitrophenyl carbonates with quinuclidines [PDF]

open access: yesTetrahedron, 2006
The reactions of quinuclidines with phenyl, 4-methylphenyl, and 4-chlorophenyl 2,4-dinitrophenyl carbonates are kinetically evaluated in aqueous solution. The Bronsted-type plots (log k(N) vs pK(a) of quinuclidinium ions) are linear. The magnitude of the

The Chemistry of Quinuclidine

Russian Chemical Reviews, 1969
The review deals with the chemical properties and the biological activity of the derivatives of 1-azabicyclo[2,2,2]octane widely known as quinuclidine. The work of the Soviet School of Chemists, founded by M.V.Rubtsov, in the field of quinuclidine derivatives is reviewed in detail.

Directed lithiation on the quinuclidine ring system: the synthesis of 2,3-difunctionalised quinuclidines

Tetrahedron Letters, 2008
Lithiation of 3-methoxymethyl quinuclidine N-oxide occurs regioselectively to generate the 2-lithio 3-methoxymethyl derivative which can be trapped out with non-enolisable electrophiles to give 2,3-disubstituted quinuclidine N-oxide derivatives in good yield.
