Title Design and synthesis of guanidine containing cyclic amine and its nitro derivatives
Abstract
Guanidine containing cyclic amine and its nitro derivatives belong to nitrogen heterocyclic compounds,which is widely used in the field of energetic materials. A "565" ring structure guanidine containing cyclic amine and its nitro derivatives is designed and synthesized in this paper.Taking glyoxal and formamideas starting materials, 2,3,5,6-tetrahydroxypiper azine-1,4- dicarbaldehy was synthesised.The reaction of 2,3,5,6-tetrahydroxyl piperazine-1,4-dicarb aldehy with guanidine hydrochloride in hydrochloric acid can be controlled to give 2,6-diimino dodecahydrodiimidazo[4,5-b:4',5'-e] piperazine. Treatment of the synthesized "565" ring with nitric acid/acetic anhydride gives title compound and its intermediates were characterized by IR, NMR and MS.The factors like reaction time, reaction temperature and the concentration of hydrochloric acid effecting condensation reaction and nitration reaction were investigated through single factor experiments.
Keywords: organic chemistry，nitration，condensation reaction， synthesis.
