قمنا بتصنيع بعض المركبات الجديدة بدءاً من 2-استيل فلورين و بارا فينيلين دي أمين حيث تم تحضير أساس شيف جديد المركب (1) بدءاً من (2-أستيل الفلورين/ بارا فنيلين دي أمين) عبر تفاعل التكاثف، ثم حضر صباغ آزو ميتين فلوريني المركب (2) و نتج عنه أساس شيف جديد المركب (3) بدءاً من أساس شيف المحضر سابقاً من خلال تفاعل تكاثف بين أساس شيف و 5،2- ثنائي هيدروكسي بنز ألدهيد.
حضرنا أساس شيف جديد المركب (4) بدءاً من (أساس شيف المحضر سابقاً المركب (1) و 5،2- ثنائي هيدروكسي بنز ألدهيد) عبر تفاعل التكاثف. ثم حضرنا مشتقات فلورينية جديدة لحلقة β-اللاكتام المركب (5) و لحلقة التيازوليدينون-4 المركب (6) بدءاً من أساس شيف المحضر سابقاً المركب (4) مع كل من كلورو أستيل كلورايد و مركبتو حمض الخل على الترتيب عبر تفاعلات التحلق.
Aseries of Schiff base and their derivative (fluorene) have been synthesized primary
amines was condensed with 2-acetyl fluorene in DMF (dimethyl formamide) in the
presence of conc. HCl acid as catalyst to yield the Schiff base (1). The Schiff base (2,3)
and (4) were prepared from the reaction of Schiff base (1) with 2-hydroxy-5-methyl-1,3-
benzenedicarboxaldehyde and 2,5-dihydroxy benzaldehyde respectively. and The Schiff’s
base (4) was treated with monochloroacetyl choride to give 1- substituted-4(2-fluorenyl)-3-
chloro Azolidine-2-on (5).
