When treated with strong acids, the N-(2-thiocyanatoethyl)-o-phenylenediamines (1g-1v) are cyclized exclusively to 3-(2-aninophen- yl)-2-iminothiazolidines (6) while the related tertiary amines (1a-1f) gave, under the same conditions, benzothiadiazocines of types (2) or (3). Some of the type (6) compounds are highly active antidepressants of low toxicity. Thermal reactions of compound (6b) and its
当用强酸处理时,N-(2-硫氰基乙基)-邻苯二胺(1g-1v)仅环化成3-(2-阴离子基)-2-亚氨基噻唑烷(6),而相关的叔胺(1a -1f)在相同条件下得到类型(2)或(3)的苯并噻二唑啉。某些类型(6)的化合物是低毒的高活性抗抑郁药。还报道了化合物(6b)的热反应及其转化为类型(22)和(24)的三环化合物。
