The reaction of 3-phenyl-1-azabicyclo[1.1.0]butane (1a) with chlorodithio-formates (5) at room temperature yielded 3-chloro-3-phenylazetidine-1-carbodithioates (6). The same products were obtained in a two-step procedure by treatment of 1a with thiophosgene to give azetidine-1-carbothioyl chloride (7a), followed by treatment with the corresponding sulfane. 3-Chloro-3-phenylazetidine-1-thiocarbamides
3-苯基-1-氮杂双环[1.1.0]丁烷 (1a) 与氯代二硫代甲酸酯 (5) 在室温下反应生成 3-氯代-3-苯基氮杂环丁烷-1-碳二硫代酸酯 (6)。通过用硫光气处理 1a 得到氮杂环丁烷-1-硫代硫酰氯 (7a),然后用相应的硫烷处理,以两步程序获得相同的产物。3-Chloro-3-phenylazetidine-1-thiocarbamides (8) 和相应的 O-甲基 1-carbothioates (9) 分别通过化合物 (7) 与胺和甲醇的反应制备。这些反应开辟了获得氮杂环丁烷-1-羧酸衍生物的新途径。
