Abstract

Synthesis of new 6‐(4‐chlorophenyl)perhydro‐1,3‐diazepine‐2,4‐diones was accomplished starting from 4‐amino‐3‐(4‐chlorophenyl)butyric acid (Baclofen). The chemical pathway involved the cyclisation of various 3‐(4‐chlorophenyl)‐4‐ureidobutyric acids. However, none of the new derivatives retained the anticonvulsant activity of their six‐membered ring homologues, belonging to the phenylpyrimidinedione series which we recently described.
