Synthesis and Investigation of (Five, Six, Seven and Eight)–Membered Rings Containing Di Nitrogen Atoms.

In this paper, series of cyclic compounds containing di nitrogen atoms in their structure were synthesized by condensation reactions which involved reaction between di amine compounds with ketone compounds to yield (5, 6, 7 and 8) –membered rings like (diazepine compounds, amide cycles, imine cycles), some of them via aldol reaction like compounds [1–8] and other reaction via cycloaddition like compounds [9–12]

All formatted compounds [1–12] were characterized by spectroscopic methods [FT.IR –spectra, H.NMR –spectra, elemental analysis (C.H.N)] and measurement their melting points.
