摘要
N-芳基-2-[(吡啶-4-基)羰基]氨基硫脲1a~1e用NaOH溶液环合,得到3-巯基-4-芳基-5-(吡啶-4-基)-1,2,4-三唑(2a~2e),经酯化,肼解,得S-{[4-芳基-5-(吡啶-4-基)]-1,2,4-三唑-3-基}巯乙酰肼(3a~3e),再与3-甲酰基色酮(4a~4d)反应,合成得到了一系列新化合物5a~5e,6a~6e,7a~7e,8a~8e.化合物的结构经元素分析,IR,1HNMR和MS谱确证.
A series of new compounds 5a-5e, 6a-6e, 7a-7e and 8a-8e were synthesized though condensation reaction of 3-formylchromones 4a-4d with S-{[4-aryl-5-(pyrid-4-yl)]-1,2,4-triazol-3-yl}- mercaptoacetylhydrazine (3a-3e) which were obtained by esterification and hydrazinolysis from 3-mercapto-4-aryl-5-(pyrid-4-yl)-1,2,4-triazoles (2a-2e) cyclized from N-aryl-2-[(pyrid-4-yl)-carbonyl] thiosemicarbazide (1a-1e) in NaOH solution. Their structures were established by elemental analysis, IR, ^1H NMR and MS spectra.
