Synthesis of poly-N-nitro-pentaazapropellane derivatives

초록

In order to produce highly energetic compounds, there have been some efforts for the synthesis of strained or caged polycyclic molecules such as adamantane, cubane, and isowurtzitane, which have significantly higher density and more potential energy than the corresponding acyclic or monocyclic compounds. Particularly, their polynitro derivatives such as TNA, nitrocubane and HNIW have the properties of high explosives. We wish to present novel polynitro derivatives with a caged pentaazapropellane structure, which are to be developed as high explosives. Glycouril diethylester, obtained from dihydroxyfumaric acid according to the literature, is converted into the unsubstituted tricyclic pentaaza-[3.3.3]-propellane, which is treated under the polynitration reaction conditions to produce their polynitramine derivatives.
