Currently, fused aza-polynitrocyclic compounds have gained considerable prominence as novel energetic compounds. This review focuses on the synthesis of various ring skeletons of the aza-bicyclic, aza-polycyclic and aza-propellane-derivatized energetic compounds as well as the studies of N-nitration, physicochemistry and detonation properties. The synthesis of pentaaza[3.3.3]propellane and hexaaza[3.3.3]propellane is highlighted and N-nitration explorations of these high-strained unstable skeletons are discussed in details.
