for the synthesis of the many fold 1,2,3-selenadiazole aromatic derivatives 5a-d. The preparation starts with the reaction between the many fold bromomethylene benzene derivatives 1a-d and 4-hydroxyacetophenone, which are transformed through the reaction with semicarbazide hydrochloride or ethylhydrazine carboxylate into the corresponding semicarbazones derivatives 3a-d or hydrazones 4a-d. The reaction
许多折叠的芳香族酮2a-d是用于合成许多折叠的1,2,3-硒代二唑芳香族衍生物5a-d的通用化合物。制备从许多倍的溴亚甲基苯衍生物1a-d与4-羟基苯乙酮的反应开始,它们通过与氨基脲盐酸盐或乙基肼甲酸乙酯反应而转化为相应的氨基脲衍生物3a-d或4a-d。与二氧化硒的反应导致半咔唑或的区域特异性闭环,以高收率得到许多折叠的1,2,3-硒代二唑芳香族衍生物。
