Heteroadamantanes and their derivatives. 7. Synthesis and mass-spectrometric study of functional derivatives of 5-mono- and 5,7-disubstituted 1,3-diazaadamantanes

The chemical behavior of the carbonyl group of 5-mono and 5,7-disubstituted 6-oxo-1,3-diazaadamantanes was studied. The structures of the functional derivatives obtained were confirmed by IR and ¹H and ¹³C NMR spectral data. The behavior of the compounds under the influence of electron impact was studied, and the principal pathways of fragmentation of their molecules were ascertained.See 1] for Communication 6.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 5, pp. 647–653, May, 1989.
