Abstract
p-Sulphonic-N-propionyl aniline 3 was produced from sulphanilic acid with propionic acid under reflux for 2 h, then the compound 3 reacted with thionyl chloride and the corresponding imidoyl chloride 4 was obtained. When imidoyl chloride 4 reacted with potassium isothiocyanate and aniline, the corresponding thiourea derivatives 6 was produced. Compound 6 was reacted with tricyanovinylamine to produce the thiazole derivative 7 after cyclization. The microwave-assisted condensation of 2,3,4.6,-tetra-O-acetyl-β-D-glucopyranosylisothiocynate 8 with thiazole derivative 7 afforded the thiourea derivatives 9. Compound 10 a, b has been synthesized by reacting thiourea derivatives 9 with chloroacetone. The prepared compounds were screened for antibacterial properties against Staphylococcus aureus and Escherichia coli, and antifungal activity against Candida sp. The structure assignments of the new synthesized compounds are based on spectroscopic data.
