    Description / Table of Contents: The four isomeric 3-dimethylamino-trans-2-decalols-1,1,4,4-d4 have been synthesised. Examination of PMR spectra of these compounds allows us to confirm the ‘flattened-chair’ conformation for the cis N(CH3)2a OHe isomer, whereas the remaining three conserve the double chair conformation. The same type of flattening is also observed in the case of the diaxial quaternary ammonium salt and is even more marked in the cis N(CH3)3a OHe isomer resulting in a ‘twist-chair’ conformation.
    Notes: Les quatre tétradeutério-1,1,4,4 diméthylamino-3 décalols-2 trans ont été synthétisés. L'examen des spectres de RMN de ces composés permet de confirmer la conformation ‘chaise aplatie’ de l'isomère cis à groupement diméthylamino axial et hydroxyle équatorial, tandis que les autres d'ammonium quaternaires on note également une déformation dans le cas du composé diaxial, cette déformation est accentuée dans l'iodure d'ammonium quaternaire cis N(CH3)3a OHe, conduisant à la conformation ‘chaise croisée’.

    Description / Table of Contents: Examination of PMR spectra of the four 3-dimethylamino-trans-2-decalols and the corresponding quaternary ammonium iodides allows the suggestion to be made that the ordinary double chair conformation usually admitted for trans-decalin is disurbed in the above compounds, especially when the amino and hydroxy groups are (a, e); truer conformations would, in fact, be better represented as ‘flattened chair’ in the case of the dimethylamino compound and ‘twist chair’ in the case of the quaternary ammonium salt.
    Notes: L'examen des spectres de RMN des quatre diméthylamino-3-décalols-2-trans et des iodures d'ammonium quaternaires correspondants permet d'envisager pour ces composés une déformation de l'un des cycles de la décaline trans habituellement double chaise.Cette déformation est apparente specialement dans le cas de l'isomère cis à groupements hydroxyle equatorial et diméthylamino axcial, pour lequel on propose une conformation ‘chaise aplatie'. Le passage à l'ammonium quaternaire accentue entre deformation jusqu’à la conformation chaise-bateau ou préférentiellement chaise croisée.

    Description / Table of Contents: The 13C NMR spectra of 2-dimethylaminocyclohexanols and the four trans-3-dimethylamino-2-decahydronaphtols are described. The gauche interactions allow precise estimation of chemical shifts for each carbon atom; thus, band attribution can be resolved without mistake. In the case of the cis and the trans diequatorial compounds, the conformational perturbations which we have suggested before are verified by our present measurements on the substituted carbon atoms. We also show effects on adjacent atoms, which were unobservable with the usual IR and 1H NMR techniques.
    Notes: Les spectres RMN du 13C de diméthylamino-2 cyclohexanols, des quatre diméthylamino-3 décahydronaphtols-2 trans et de leurs iodures d'ammonium quaternaires sont décrits. Le calcul des séplacements chimiques de chaque carbone en tenant compte des interactions gauches permet d'attribuer correctement chaque signal. Dans le cas des composés cis ou trans diéquatorial, on a pu non seulement vérifier des modifications conformationelles portant sur les carbones substitués, mais on a pu mettre également en évidence des effects portant sur les carbones voisins, effets que les méthodes IR et RMN du proton ne pouvaient pas permettre d'observer.
