3.1) NONANE FRAGMENT. FIELD: chemical industry. SUBSTANCE: described is method of preparing amino acids containing 3-azabycycle (3.3.1) nonane fragment of general formula: 
wherein 
. Original 1-R1-2,4- and 1-R2-3,5- dinitrobenzenes are reduced with KBH4 to corresponding 3,5-bis-acy-nitro) cyclohexene-2 dipotassium salts followed by condensation by manich reaction with formaldehyde and amino acids at pH of 6. Polyfunctionality of the resulting compounds offers possibilities of wide chemical modification of substituted and functional groups therein with view of improving properties thereof. EFFECT: more efficient preparation method. 3 tbl
