Iminodibenzyl derivatives of the formula: ##SPC1## Wherein R and R.sup.1 each represent hydrogen, halogen, amino, sulfamoyl, lower alkyl, lower alkoxy or lower alkanoyl, provided that R and R.sup.1 can not both be hydrogen and when R and R.sup.1 are the same, they are located at positions asymmetric to each other, are produced in high purity and yield by a series of reactions which proceed through novel 2,2'-dinitrostilbene or 2,2'-diaminostilbene and 2,2'-diaminodibenzyl derivatives. The reaction sequence involves condensation, reduction and ring-closure reactions to give asymmetric as well as symmetric iminodibenzyl derivatives. The resulting iminodibenzyl derivatives may be converted to useful pharmaceutical compounds having anti-depressant, analgesic or anti-allergic properties.
公式为:##SPC1## 其中R和R.sup.1分别代表氢、卤素、氨基、磺酰胺基、低烷基、低烷氧基或低烷酰基,但要求R和R.sup.1不能同时为氢,当R和R.sup.1相同时,它们位于不对称位置。通过一系列反应,包括新型的2,2'-二硝基亚苯基或2,2'-二氨基亚苯基和2,2'-二氨基二苯基衍生物的缩合、还原和环闭反应,高纯度和高收率地制备了不对称和对称的亚胺二苯基衍生物。所得的亚胺二苯基衍生物可以转化为具有抗抑郁、镇痛或抗过敏性能的有用药物化合物。
