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.
