本文用芳酰肼和2,2,6,6-四甲基-4-异硫氰基-哌啶-1-氧以无水乙醇为溶剂,在氩气保护下反应,制得八种1-芳酰基-4-[4'(2,2,6,6-四甲基哌啶-1-氧)]氨基硫脲(1),继而研究1在几种碱催化下脱水的环化反应。试验结果表明,只有在1mol的K2CO3水溶液中,才能较满意地使1环化,得到预期的3-芳基-4-(4'-2,2, 6,6-四甲基哌啶-1-氧)-1,2,4-三唑啉-5 硫酮。

The synthesis of eight new 3-aryl-4-(4'-2,2,6,6-tetramethylpiperidine-1-oxyl)-1,2,4-triazoline-5-thion es I (R = Ph, substituted Ph) and the characterization of their structure were reported. Preliminary pharmacodynamic experiments of these compounds showed that most of them possess inhibiting effect on Bacillus subtilis, Escherichia coli, Proteus vulgaris, and Staphylococcus aureus.
