报道了两种新含硫席夫碱──维生素Ｋ３单缩二氨基硫脲和丙酮酸二缩二氨基硫脲的合成。这两种化合物至今尚未见文献报道。通过元素分析、质谱、红外光谱和核磁共振氢谱对两种化合物的结构进行了表征。
Two novel sulfur-containing Schiff bases - the synthesis of vitamin K3 mono-thiosemicarbazone and pyruvic acid di-thiosemicarbazide were reported. These two compounds have not been reported in the literature. The structures of the two compounds were characterized by elemental analysis, mass spectrometry, infrared spectroscopy and proton nuclear magnetic resonance spectroscopy.
