Abstract: | Heating 1,5-dinitro-3,7-di(tert-butyl)-3,7-diazabicyclo3.3.1]-nonane with concentrated hydrobromic acid gives 1,5-dinitro-3,7-diazabicyclo3.3.1]nonane. Cyclization of the latter with various aldehydes and ketones gave a series of 2,2-disubstituted 5,7-dinitro-1,3-diazaadamantanes. The behavior of the synthesized compounds under electron impact has been studied.For Communication 8 see 1].Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 4, pp. 538–542, April, 1990. |
