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.
揭示了在位置4处具有烷基胺取代基的4H-吡咯并[2,1-c][1,4]苯并氧嗪和4H-吡咯并[2,1-c]-[1,4]苯并噻嗪。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,这些化合物可能在位置1和6至9处被选择性取代。还揭示了在位置4处被二烷基化且在位置1处具有甲基氨基取代基的4H-吡咯并[2,1-c][1,4]苯并氧嗪和4H-吡咯并[2,1-c][1,4]苯并噻嗪。上述化合物具有降压和中枢神经抑制活性,并描述了它们的制备和使用方法。
