We studied methods of stereospecific synthesis that enabled us to obtain variously substituted morpholinic compounds and to determine their absolute configuration.From a study of the chiroptical properties of synthetic N-(2-pyridyl-N-oxide) derivatives of optically active morpholines, it was possible to correlate the sign of the Cotton effect with the absolute configuration.This correlation agrees with that previously established for derivatives of the piperidine type.By evaluating the various contributions to the Cotton effect of substituents in positions 2 and 3, we established the absolute configuration of bicyclic compounds condensed in the two positions mentioned above.
