Several 3,7-diheterabicyclo[3.3.1]nonanes (DHBCNs) were prepared and screened in the Harris dog model for their ability to abolish pace-induced and sustained ventricular tachycardia (SVT) or prevent induction of ventricular tachycardia. In addition, an electrophysiological examination was made in
Synthesis and antiarrhythmic properties of novel 3-selena-7-azabicyclo[3.3.1]nonanes and derivatives. Single-crystal X-ray diffraction analysis of 7-benzyl-3-selena-7-azabicyclo[3.3.1]nonan-9-one and 7-benzyl-3-selena-7-azabicyclo[3.3.1]nonane hydroperchlorate.

Several members of the heterocyclic family 3-selena-7-azabicyclo[3.3.1]nonane have been synthesized and characterized via IR, 1H, 13C, 15N, and 77Se NMR spectroscopy and, in some cases, by X-ray diffraction analysis. Select members, namely the hydroperchlorates of the amines, were examined for
Synthesis, conformational analysis, and antiarrhythmic properties of 7-benzyl-3-thia-7-azabicyclo[3.3.1]nonan-9-one, 7-benzyl-3-thia-7-azabicyclo[3.3.1]nonane hydroperchlorate, and 7-benzyl-9-phenyl-3-thia-7-azabicyclo[3.3.1]nonan-9-ol hydroperchlorate and derivatives: single-crystal X-ray diffraction analysis and evidence for chair-chair and chair-boat conformers in the solid state.
