Azatriquinane, an amine with a rigid, hemispherical topology, is synth
esized in six steps from pyrrole. It is shown to be more basic than qu
inuclidine, and can be dimerized by N-oxidation and treatment with bas
e to give novel, highly strained heptacycle. Oxidation with chlorine g
ives an azatriquinacene, a theoretical precursor to diazadodecahedrane
.
