Abstract
Three isomers of 1,2-dimethyldecahydroquinolin-5-ol and their acetates with cis and trans fusion of the rings and different orientations of the hydroxy and acyloxy groups were obtained. The correlation of the frequencies of the C-O, O-H, and N+-H stretching vibrations with the configurations of these compounds was studied. The 1,2-dimethyl-cis-decahydroquinolin-5-ol isomer with a syn orientation of the amino and hydroxy groups exists in a conformation with an intramolecular hydrogen bond, the character of which is determined by the functional state of the amino group (OH...N in the base and N+-H...O in the hydrochloride). The hydrochloride of the acetate of this alcohol does not form an intramolecular N+-H...O(COCH3) bond.
