Various new N-aryl oxindoles were synthesized as intermediates for the preparation of pharmacologically active 2-(N-arylamino)-phenylacetic acids. Two novel approaches were explored for the construction of diarylamine and N-aryl oxindole core structures, in addition to Buchwald-arylamination and Smiles rearrangement. Condensation of anilines with 2-oxo-cyclohexylidene-acetic acid derivatives and subsequent
合成了各种新的N-芳基羟吲哚作为制备药理活性的2-(N-芳基氨基)-苯乙酸的中间体。除了布赫瓦尔德-芳基化和Smiles重排以外,还探索了两种新颖的方法来构建二芳基胺和N-芳基羟吲哚核心结构。苯胺与2-氧代-环己叉基-乙酸衍生物的缩合反应以及随后的脱氢反应是制备N-芳基羟吲哚的一种新的可行方法。
