         This work involves synthesis and biological activity of some amino and barbituric acid derivatives via shiff bases. This work is divided into six different parts:
 Part One:
         This part involved the synthesis of different shiff bases [1] by reaction of the aniline with benzaldehyde and its derivatives.
Part Two:
          This part involved synthesis of phenoxy acetic acid [II] which converted to phenoxy acid chloride [Ш]. Reaction of the latter compound with shiff bases resulted in part one yields acetanilide derivatives
Part Three:
  This part involved synthesis of amino acid derivatives [3, 4, and 5] by reaction of acetanilide derivatives resulted in part two with different of L-amino acids (Cysteine, Valine, Phenylalanine) as shown in scheme [I].  
 Part Four:
  This part involved synthesis of barbituric acid derivatives [7] by reaction of acetanilide derivatives resulted in part two with guanidine carbonate and diethyl malonate (DEM) as shown in scheme [II].  
Part Five:
          This part involved characterization of the products above by their melting points, elemental analysis and FTIR spectroscopy listed in table 4, 9, and 11.
Part Six:
        This part involved the evaluation of antibacterial activity of the products. These activities were determined in vitro using disc diffusion method against two pathogenic strains of bacteria {Pseudomonas
aeuroginosa and Staphylococcus aureus}, as shown in table (4-1).
