A convenient synthesis of the 2-carboxyalkyl-1,2-benzisoselenazol-3(2H)-ones 4a–k and their esters 41–p from 2-(chloroseleno)benzoyl chloride (2) and amino acids or their carboxy esters is reported. In similar way other 2-substituted 1,2-benzisoselenazol-3(2H)-ones 4q–u were synthesized. The related bis[2-(carbamoyl)phenyl] diselenides 5 were obtained by reductive conversion of 1,2-benzisoselenazol-3(2H)-ones
由2-(氯硒代)苯甲酰氯(2)和氨基酸或其羧基酯方便地合成2-羧烷基-1,2-苯并咪唑-3(2 H)-酮4a–k及其酯41–p为:报告。以类似的方式,合成了其他2-取代的1,2-苯并亚硒唑-3(2 H)-酮4q–u。相关的双[2-(氨基甲酰基)苯基]二硒化物5是通过1,2-苯并硒代咪唑-3(2 H)-ones 4的还原转化或直接通过双[2-(氯羰基)苯基]二硒化物的反应获得的。3)具有伯氨基的化合物。发现一些化合物41和5是人外周血白细胞培养物中适度的细胞因子(TNF,IFN)诱导剂,可阻断本构性内皮一氧化氮合酶(ce NOS)。
