Diazabicycloalkanes with nitrogen atoms in the nodal positions. 6. Synthesis and some properties of benzo[f]-1,5-diazabicyclo[3.2.2]nonene and benzo[g]-1,6-diazabicyclo[4.2.2]decene

The reaction of N-acetyl derivatives of N,N-trimethylene- and N,N-tetramethylene-o-phenylenediamines with ethylene oxide gave the corresponding N-(-hydroxyethyl)-N-acetyl derivatives, the cyclization of which in refluxing hydrobromic acid leads to benzo[f]-1,5-diazabicyclo[3.2.2]nonene and benzo[g]-1,6-diazabicyclo[4.2.2.]decene.See [1] for Communication 5.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 11, pp. 1538–1542, November, 1981.
