Abstract
Original methods of synthesizing N-substituted 2-methyl-5-(1-methylethyl)cyclohexylamines by hydroamination reactions of (+)-S-carvone with aliphatic nitriles and the hydroamination of some aldehydes and ketones with (+)-S-carvone oxime have been developed. The optimum conditions for performing these processes has been selected. It has been established by13C NMR that the reactions studied form a mixture of N-substituted carvo-, isocarvo-, neocarvo-, and neoisocarvomenthylamines in a ratio of 65:20:10:5. As a result of the investigation, 11 secondary amines of the p-menthane series not previously described in the literature have been isolated and characterized. The absolute configurations of the compounds synthesized have been determined.
