The Synthesis of 1-(1-Phenyl-1H-tetrazole-5-ylthiol)-acetyl-4-aroyl-thiosemicarbazides and 2-Aroylamino-5- (1-phenyl-1H-tetrazole-5-ylthiolmethylene)- 1,3,4-thiadiazoles
摘要:
A series of 1-(1-phenyl-H-1-tetrazole-5-ylthiol)acetyl-4-aroylthiosemicarbazides were synthesized in good to excellent yields under phase transfer catalytic conditions. By the cyclization of compounds 3a-i in concentrated H2SO4 at 0 degrees C,2-aroylamino-5-(1-phenyl-H-1-tetrazole-5-ylthiolmethylene)-1,3,4-thiadiazoles were obtained in high yields. The structures of the products were established by elemental analysis, IR, H-1 NMR, and C-13 NMR.
