Synthesis of nitrogen-containing dispiroheterocycles using nitrilimines (II)

Abstract

A series of 1,2,4,9,10,12-hexaazadispiro[4.2.4.2]tetradeca-2,10-dienes (5a-j) was synthesized by the reaction of 1,4-cyclohexanedione oxime 3 with appropriate nitrilimines 2. The microanalysis and spectral data of the synthesized compounds are in full agreement with their molecular structure. The microbial features of some of the synthesized compounds were studied by a known method.
