Synthesis of N-benzyl-N-methyl-2-cyclohepten-1-amine and tert-butyl 4-[benzyl(methyl)amino]-2,3,4,7-tetrahydro-1H-azepine-1-carboxylate from cyclic allyl acetates was performed. The features of stereoselective epoxidation of these substrates were investigated. The subsequent epoxide opening with water led to the formation of new pseudosaccharides, (1RS,2RS,3RS)-3-[benzyl(methyl)amino]-1,2-cycloheptanediol, (1RS,2RS,3SR)-3-[benzyl(methyl)amino]-1,2-cycloheptanediol, and (3RS,4RS,5RS)-3-[benzyl(methyl)amino]-4,5-azepanediol.
