Synthese et etude conformationnelle de diaza-3,7 bicyclo(3.3.1)nonanones-9
1H and 13C NMR studies of various 3,7-diazabicyclo-(3.3.1)nonanones indicate an equilibrium between chair-chair and chair-boat conformations for these compounds.When the 7 nitrogen atom bears bulky substituents, the chair-boat form is more favoured at equilibrium. 13C NMR is very useful for the determination of the conformation.
