Abstract: | 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. |
