Synthesis and Crystal Structure of Some Novel 2-Aroylimino-3-aryl-4-phenyl-1,3-thiazolines
摘要:
An efficient synthesis of some novel 2-aroylimino-3-aryl-4-phenyl-1,3-thiazolines was carried out by base-catalyzed cyclization of 1-aroyl-3-arylthioureas with acetophenone in the presence of bromine. The structures were confirmed by spectroscopic data, elemental analyses, and in one case (2t) by single-crystal X-ray diffraction data.
在这项工作中,我们报道了基于酰化硫脲的2 H -1,3,5-恶二嗪-2,4(3 H )-二亚胺衍生物的合成。1,3,5-恶二嗪衍生物的制备方法是以酰化硫脲为起始原料,在二环己基碳二亚胺(DCC)作用下进行脱氢硫化反应,再与另一个DCC分子进行[4+2]环加成反应。所得中间体碳二亚胺。所得1,3,5-恶二嗪衍生物的结构通过1 H, 13 C NMR、IR光谱、质谱和X射线衍射分析证实。
