A novel route for the conversion of anilides into 3-alkyl-oxindoles is described in which a copper(II)-mediated cyclization process is followed by an acid-mediated decarboxyalkylation. Scope and limitation studies are reported together with a telescoped variant which incorporates in situ N-deprotection.
介绍了一种将
苯胺转化为 3-烷基-氧
吲哚的新方法,其中先进行
铜(II)介导的环化反应,然后再进行酸介导的脱羧基烷基化反应。报告了范围和局限性研究,以及结合了原位 N-脱保护的伸缩变体。
