تحضير 1، 3 ديازابين 4-7 دايون المماثل للـ (الفاليوم) الذي يستعمل كعامل للسيطرة على القلق وحالات التوتر ومضاد الكآبة.

الملخص

Oxazepine [1] is non – nomologous seven –member ring  that contain two netroatoms (oxygen and nitrogen ). Meanwhile diazepine [2] contains to nitrogen atoms in seven – member  ring.

                   

Diazepam (valium) [3] is used to relive anxiety tension associated with anxiety disorder and muscle spasms ^{(1, 2, 3)} as well as alcohol withdrawal, and other clinically uses.

oxazepam (serax) [4] is a new benzodiazepine derivative introduced in 1965 for use in the relief of psychoneuroses characterized by anxiety and tension. It is said show a lower incidence of side – effect and reduced toxicity.

A sendin (amoxapine) [5] is an antidepressant with a mild sedative component to its actor. The mechanism of its clinical action in human is not well understood. In animals, amoxapine reduced the uptake of receptors to dopamine.

Many researchers ^{(4, 5, 6, 7}) employed a pericyclic reaction to synthesize oxazepine derivatives.

1. A. Hussein etl .al ^{(6, 7)} prepared N – Cinna mulidene aren amine [I] by condensation of cinnamaldehyde with primary aromatic amine and were react with maleic anhydride [scheme 1].

In this work a 1, 2, 3 –substitued – 1, 3 oxozepine - diazepine – 4, 7 0diones (III) was obtained by reaction of 1.3 -4.7 dione (II) with ammonia derivative [Scheme 1].
