A series of 22 aromatic aldehyde/ketone 4-(beta-D-glucopyranosyl)thiosemicarbazones have been synthesized by condensation of 4-(per-O-acetylated-beta-D-glucopyranosyl)thiosemicarbazide with an aldehyde or a ketone, and then, deacetylation of the resulting product. The compounds were fully characterized by spectroscopic techniques, elemental analysis, and for two derivatives by X-ray analysis. The data
通过将4-(全-O-乙酰基化的β-D-吡喃葡萄糖基)硫代氨基脲与醛或酮缩合,合成了一系列22种芳香族醛/酮4-(β-D-吡喃葡萄糖基)硫代半碳唑酮,然后,所得产物脱乙酰化。通过光谱技术,元素分析和X射线分析对两种衍生物进行了全面表征。数据指示β构型,以及与C = N键的立体化学有关的E构型。但是,几个小时后,溶液中E形可能会部分转化为Z形。
