Synthesis of 3-[4-({Methyl-5-[(E)-2-phenyl-1-ethenyl]-4-isoxazolyl}amino)-1,3-thiazol-2-yl]-2-aryl-1,3-thiazolan-4-ones as Potential Biodynamic Agents
摘要:
A series of isoxazolyl thiazolyl thiazolidinones (4a-h) were synthesized starting from isoxazolyl chloroacetamide 1. Compound 1 upon heating with thiourea in ethanol furnished N4-{3-methyl-5-[(E)-2-phenyl-1-ethenyl]-4-isoxazolyl]-1,3-thiazole-2,4-diamine 2. Condensation of 2 with aromatic aldehydes afforded corresponding Schiff bases (3a-h), which undergo cyclocondensation on treatment with mercaptoacetic acid to give 3-[4-({methyl-5-(E)-2-phenyl-1-ethenyl]-4-isoxazolyl] amino)-1,3-thiazol-2-yl]-2-aryl-1, 3-thiazolyl -4-ones (4a-h) in excellent yields. Structures of all the synthesized compounds have been established by elemental analyses, IR, 1H NMR, and mass spectral data.
