Abstract
The original work of the thesis consists of four sections. The first section deals with the synthesis of β-acylaminoketones containing a thiophene ring by the use of tetrachlorosilane/zinc chloride binary mixture as an efficient reagent. The second section of the thesis deals with the use of same reagent under different condition to synthesis some new β-acylaminoketones with poly nuclear moieties. Section three of the thesis aims to the synthesis of some new 1,3-oxazine derivatives via the reaction of substituted cyclohexanone, aldehyde, and nitrile with the same binary reagent. Section four of the thesis studies the biological activity of some newly synthesized compounds and shows that antibacterial and antifungal activities. The thesis is well written, experimental are clearly described and structures of newly synthesized compounds are well proved. .
