Synthesis and transformations of polyhedral compounds. Synthesis of 2-[quinolin-3(2)-yl]-1,3-diazaadamantanes

A number of new 1,3-diazaadamantane derivatives containing quinoline fragments on C2 have been synthesized by condensation of 1,5-dialkyl-3,7-diazabicyclo[3.3.1]nonan-9-one, 1,5-dimethyl-3,7-diazabicyclo-[3.3.1]nonan-9-ol, and 1,5-dimethyl-3,7-diazabicyclo[3.3.1]nonane with 2-oxo-1,2-dihydroquinoline-3-carbaldehyde, 2-chloro- and 2-iodoquinoline-3-carbaldehyde, and quinoline-2-carbaldehyde.
