Abstract
Abstract The infrared, 1 H and 13 C NMR spectra of 9-(2′-hydroxyethyl)-9-azabicyclo[3.3.1] nonan-3α-ol (I) have been examined in several media. The crystal structure has been determined by X-ray diffraction. The bicycle system adopts in solid state a distorted double chair conformation, being the OH and 2′-hydroxyethyl group attached in axial position with respect to the piperidinol ring. In solution, by the contrary, the title compound adopts a preferred flattened chair-boat conformation with the piperidinol ring in a slight distorted boat form. The unambiguous assignment of all protons of the granatanine system, not described up to date, has been carried out.
