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##的Iminodibenzyl衍生物:其中,R和R.sup.1分别代表氢,卤素,氨基,磺酰胺基,较低烷基,较低烷氧基或较低烷酰基,但要求R和R.sup.1不能同时为氢,当R和R.sup.1相同时,它们位于彼此不对称的位置,通过一系列反应,包括新型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,高纯度和产量的生成。反应序列涉及缩合、还原和环闭合反应,以得到不对称和对称的iminodibenzyl衍生物。由此产生的iminodibenzyl衍生物可以转化为具有抗抑郁、镇痛或抗过敏特性的有用药物化合物。
