A new series of 4-(4-methylpiperazin-1-yl)thieno[2,3-b][1,5]benzoxazepines 1a-k has been synthesized from 4-bromo-2-methylthiophene 6 or ethyl 2-amino-4,5-dimethyl-3-thiophencarboxylate 10. Preparation of the key intermediate thieno[2,3-b][1,5]benzoxazepine-4(5H)-ones 4a-i, 4k were carried out by treatment of 2-bromo-N-(2-hydroxyphenyl)-3-thiophencarboxamides 5a-i, 5k with potassium carbonate in DMSO
由4-溴-2-甲基噻吩6或乙基2-氨基-苯甲酸酯合成了一系列新的4-(4-甲基哌嗪-1-基)噻吩并[2,3- b ] [1,5]苯并a庚因1a-k。 4,5-二甲基-3-噻吩羧酸盐10。关键中间体噻吩并[2,3- b ] [1,5]苯并x氮平-4(5 H)-的制备4a-i,4k是通过2-溴-N-(2-羟苯基)-的处理3-硫代苯甲酰胺5a-i,5k与碳酸钾的DMSO溶液。化合物1是洛沙平(一种有效的抗精神病药物)的噻吩类。在这些化合物中,2-甲基-4-(4-甲基哌嗪-1-基)噻吩并[2,3-b ] [1,5]苯并a庚因1a(R 1,R 3 = H,R 2 = CH 3)显示出有效的抗精神病活性。
