Synthesis of some new sodium Saccharine derivatives

The present work involves the synthesis of some new heterocyclic compounds derived from saccharin salt as a starting material. This work wasdivided into four parts. Part One: This part includes synthesis of N-propergel saccharine alkyl azides 123-triazole derivatives and hydrolysis of 123-triazoles. Part Two: this part include synthesis of new heterocyclic derivatives of Schiff bases hydrolysis of Schiff bases and chalcone derivatives bearing 123-triazoles moieties. Part Three: this part include synthesis of new compounds such as: pyrazoline isoxazoline pyrimidin-2-one pyrimidin-2-thiol bearing on N-[1-{(p-acetylphenyl)-123-triazol-4-yl} methyl] saccharin moieties. Part Four: this part includes using some newly synthesized compounds in four different applications.
