SYNTHESIS OF VARIOUS –MEMBERED RINGS FROM (AZE-CYCLES)

Dr. Nagham Mahmood Aljamali

ABSTRACT

various membered ring) have been synthesized in present work . Some of these compound used imine & amino compounds as starting materials in their synthesis like compounds [1-4] to prepare cycles . This work involved , synthesis of oxazepine compounds [9] as (seven–membered ring) , which is used in synthesis of tri azeocine compounds [10] as (eight–membered ring) , bi cyclic compounds [11] , di azepine compounds [12,13] , di azetidine–thione& di azrine as (four or (three–membered ring)linked . with di azepine (seven–ring) like compounds [13 , 15] , formazane(azo –imine ) like compounds [6 , 22] . The structure of these compounds were characterized by (H.NMR , FT.IR , C.H.N) –Techniques & their melting points.

Keywords: Various– membered, various rings , various cycles .
