Solvent free, dry media supported synthesis of a series of 4-aryl/heteroaryl-2-methylthio-3H-1,5-benzodiazepines by chemo- and regioselective cyclization of substituted α-oxoketene dithioacetals with o-phenylenediamines is described. The X-ray crystallographic studies confirmed the formation of the cyclized product.
描述了无溶剂的干燥介质支持的合成的4-芳基/杂芳基-2-甲硫基-3 H -1,5-苯并二氮杂卓的合成,该取代基是通过邻位苯二胺对取代的α-氧杂环丁烯二硫缩醛的化学和区域选择性环化。X射线晶体学研究证实了环化产物的形成。
