Pyrrolo[1,2-a]thieno[3,2-f][1,4]diazepines were obtained in an original one step synthesis by treatment of imines 1 with paraformaldehyde in refluxing ethanol. The intermediate Mannich bases were also converted into the thienooxadiazocines 12 and the diazepine N-oxide 13.
吡咯并[1,2- a ]噻吩并[3,2- f ] [1,4]二氮杂卓是通过在回流的乙醇中用低聚甲醛处理亚胺1的原始一步合成获得的。中间的曼尼希碱也被转化为硫代恶二唑胺12和二氮杂氮氧化物13。
