benzylic position has been achieved via a 'transition-metal-free' intramolecular dehydrogenative coupling (IDC). The construction of 2-oxindole moieties was carried out through formation of carbon-carbon bonds using KOt-Bu-catalyzed one pot C-alkylation of beta-N-arylamido esters with alkyl halides followed by a dehydrogenative coupling. Experimental evidences indicated toward a radical-mediated path for
经由“无过渡
金属”的分子内脱氢偶联(IDC),已经完成了在假苄基位置带有全碳季中心的各种2-氧
吲哚的合成。通过使用KOt-Bu催化β-N-芳基酰胺酯与烷基卤化物的一锅C-烷基化,然后脱氢偶联,通过形成碳-碳键来进行2-氧
吲哚部分的构建。实验证据表明该反应朝向自由基介导的途径。
