The synthesis of the benzothiopheneanalogues of the orally active antifungal agents ketoconazole and itraconazole 3a and 3b is reported. The key heterocyclic system 3-(1-piperazinyl)benzo[b]thiophene is prepared by formation of the enamine between a benzothienone and ethyl 1-piperazinecarboxylate. After elaboration of the respective N-substituents, the methoxy group is cleaved with boron tribromide
据报道,口服活性抗真菌剂酮康唑和伊曲康唑3a和3b的苯并噻吩类似物的合成。通过在苯并噻吩酮和1-哌嗪羧酸乙酯之间形成烯胺来制备关键的杂环系统3-(1-哌嗪基)苯并[ b ]噻吩。在详细说明各个N-取代基后,用三溴化硼裂解甲氧基,并用相应的甲磺酸酯将O -alky-1烷基化。
