Synthesis and Characterization of Some Amino Acid Derivatives and Studying Its Antibacterial Activity

The present work includes the synthesis of different Schiff’s bases [3(A-C)] by the reaction of 2-Aminopyridine [2] with benzaldehyde and its derivatives   [1(A-C)]. These Schiff’s bases react with benzoyl chloride [4] to yield benzamide derivatives [5(A-C)]. The synthesis of L-amino acid derivatives [6(A-C)–10(A-C)] has been performed by the reaction of benzamide derivatives [5(A-C)] with (Glycine, L-Alanine, L-Phenylalanine, L-Asparatic acid and  L-Asparagine).
