تضمنت هذة الدراسة تحضير مشتقات حلقية غير متجانسة مثل 2 - امينو - 4 - فنيل ثيازول(2 - Amino - 4 - phenyl thiazol)، والاوكسازبين(Oxazepine)، والتريازول(triazol)، والاميدازوليدين(Imidazolidine). ابتداءا من (2 - Amino thiazol) و(Acetophenon) كمركبات اساس | This Study include synthesis of some heterocyclic derivatives such as (2 - amino - 4 - phenyl thiazol) , (oxazepine) ,(tetrazole) and (Imidazolidine) ,starting from (2 - amino thiazol) and (acetophenon) This Work is divided in to three Parts : Part one : Include Foure StepsThe first step include synthesis of 2 - amino - 4 - phenyl thiazol from (acetophenon),(thiourea ),(Iodine) ,while second step repersents the formation of Azo derivatives of (2 - amino - 4 - phenyl thiazol) ,while third step includes the formation of schiff base derivatives through reaction of azo compound with (3 - hydroxybenzaldehyde) The fourth step includes the reaction of prepared shiff base with compound (? - alanine) These steps are explain in diagram (1)Diagram No.1Part two : Includes two stepsFirst step includes the formation of schiff base derivatives of (2 - amino thiazol) through reaction of (2 - amino thiazol) with several compound , while second step includes reaction of several compounds with prepared schiff base to formate five and seven ring Theses steps are explain in diagram(2) Diagram No.(2)Part Three : Includes two stepsThe first step includes reaction of (acetylaceton) and (isatine) with (2 - amino thiazol) to formate new schiff base , while second step includes reaction several compound with prepared schiff base to formate five and seven ring.These steps are explain in Digram (3) Diagram No.3The sequence of reaction steps are followed up by (TLC) technique , and by busing solvents (methanol and benzene(1 : 4)) and ethyl acetate.All compounds are identified by (FT : IR) ,and some compounds by H1 - NMR and (C.H.N.S)
