Synthesis of nitrogen-containing dispiroheterocycles (IV) using nitrilimines

A number of new substituted 1,2,4,9,10,12-hexaazadispiro[4.2.4.2]tetra-deca-2,10-dienes have been obtained from the reaction of 1,4-cyclohexanedione hydrazones having acetyl, benzoyl, ethoxycarbonyl and methoxycarbonyl groups with appropriate nitrilimines. The microanalysis and spectral data of the synthesized compounds are in full agreement with their molecular structure. The microbial features of the synthesized compounds were studied by a known method.
