المستخلص:
تضمنت الرسالة تحضير وتشخيص عدد من مشتقات البريميدين الجديدة من خلال تطبيق تفاعل سوزوكي، كما شملت الرسالة الفعالية البايولوجية للمركبات المحضرة ضد فيروس الايدز، تم انجاز موضوع الرسالة بتطبيق الاجزاء التالية : الجزء الاول تحضير المركبات 99 , 101 , 103 , 1 | The thesis included a detailed study of the biological importance of Pyrimidines compounds. The literature screening included the synthesis of different derivatives of pyrimidines compounds as well as their chemical reactivity , in addition to the experimental part which included the chemical procedures for preparation of the new derivatives of pyrimidine. New pyrimidine derivatives have been prepared by several parts : The first part include preparation of compounds 99 , 101 , 103 , 105 , 107 , 108 , 110 , 112 , 114 , 116 by Suzuki coupling reaction via reaction of uracil derivatived with the aromatic boronic acids to give new derivatives.The second part includes preparation of pyrimidine derived 117 by nitration of compound 42 using of concentrated nitric acid with concentrated sulfuric acid and preparation of new derivatives starting from compound 117 via Suzuki coupling reaction with some aromatic boronic acids.The third part includes includes preparation of new two compounds derived from compound 120 via Suzuki coupling reaction with the different boronic acides. The fourth part includes preparation of pyrimidine derivatives 126 by reaction of pyrimidine derivatives 120 with para - chloroaniline via coupling reaction to give the new derivative of azo pyrimdine dye.The fifth part includes preparation of new two compounds derived from compound 126 via Suzuki coupling reaction with the different boronic acides.As well as the thesis which us discussed the preparation and identification of new pyrimidine derivatives from throough spectra (I.R) , (1H - NMR) , (13C - NMR) and (C.H.N) and specta (HSQC) , (COSY) and (HMBC). For some of these compounds, and these identification studies approved the correctness of the chemical structures for the prepared derivatives. As well as in the thesis is included biological activity against AIDS. Scheme (1)R NO.
