4H-Pyrrolo[2,1-c][1,4]benzoxazines and 4H-pyrrolo[2,1-c]-[1,4]benzothiazines characterized by having an alkylamine substituent at position 4 are disclosed. The compounds are characterized further by having an alkyl substituent on the same carbon atom bearing the alkylamine substituent. In addition the compounds may be optionally substituted at positions 1 and 6 to 9. Also disclosed are 4H-pyrrolo-[2,1-c][1,4]benzoxazines and 4H-pyrrolo[2,1-c][1,4]benzothiazines which are dialkylated at position 4 and have a methylamino substituent at position 1. The foregoing compounds possess antihypertensive and central nervous system depressant activity and methods for their preparation and use are described.
本文披露了在位置4上具有烷基胺基取代基的4H-Pyrrolo[2,1-c][1,4]benzoxazines和4H-pyrrolo[2,1-c]-[1,4]benzothiazines。此外,这些化合物还具有在同一碳原子上带有烷基取代基的特征。此外,这些化合物可以在1和6到9号位置进行选择性取代。本文还披露了在位置4上二烷基化并在位置1上具有甲基氨基取代基的4H-pyrrolo-[2,1-c][1,4]benzoxazines和4H-pyrrolo[2,1-c][1,4]benzothiazines。上述化合物具有抗高血压和中枢神经系统抑制活性,本文还描述了它们的制备和使用方法。
