  通过sp（2）CH和sp（3）CH键的“无过渡金属”分子内脱氢偶联（IDC）合成2-氧吲哚。

  摘要：

  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。

  An intramolecular-dehydrogenative-coupling (IDC) using "transition-metal-free" oxidation conditions has been achieved to synthesize a variety of 2-oxindoles bearing an all-carbon quaternary stereogenic center at the benzylic position. The methodology involves a one-pot C-alkylation of beta-N-arylamido esters (3, 6) with alkyl halides using potassium tert-butoxide concomitant with a dehydrogenative coupling. A radical-mediated pathway has been tentatively proposed for the oxidative process.

  An efficient route to 2-oxindoles bearing an all-carbon quaternary center at the pseudobenzylic position has been developed via a DDQ-mediated Intramolecular-Dehydrogenative-Coupling (IDC). The methodology involves a one-pot C-alkylation of beta-N-arylamido esters (7) concomitant with dehydrogenative-coupling in the presence of stoichiometric amount of DDQ. A tentative mechanistic route has been proposed for the oxidative coupling. The methodology provides a two-step entry to the ergoline structure of ergot alkaloids.
