  Catalytic Asymmetric Hydroxylation of Oxindoles by Molecular Oxygen Using a Phase-Transfer Catalyst

  摘要：

  The highly enantioselective catalytic hydroxylation of 3-substituted oxindoles was achieved by using a phase-transfer catalyst with molecular oxygen as an oxidant. The product then was converted to an optically active compound 8, which was a synthetic precursor of alkaloid CPC-1.

  3‐alkyloxindoles to phenyl vinyl sulfone has been demonstrated. This approach allows the construction of 3,3‐dialkyl‐substituted oxindole frameworks with high yield and excellent enantioselectivity (up to 99 %) under simple phase‐transfer conditions. A variety of oxindoles bearing all‐carbon quaternary stereogenic centers were obtained in the presence of 0.25 mol % pentanidium. Meanwhile, practicality was

  证明了戊烷催化的3-烷基氧吲哚向苯乙烯基砜的高对映选择性共轭加成反应。这种方法允许在简单的相转移条件下以高收率和出色的对映选择性（高达99％）构建3,3-二烷基取代的羟吲哚骨架。在0.25摩尔％的戊ani存在下，获得了各种带有全碳四元立体异构中心的羟吲哚。同时，通过两个3,3-二烷基取代的羟吲哚的克级不对称合成说明了实用性。生成的加合物可以通过短合成路线顺利转化为天然产物类似物。

  Pentanidium-catalyzed alpha-hydroxylation of 3-substituted-2-oxindoles using molecular oxygen has been developed with good yields and enantioselectivities. This reaction does not require an additional reductant such as triethyl phosphite, which was typically added to reduce the peroxide intermediate. The reaction was demonstrated to consist of two-steps: an enantioselective formation of hydroperoxide oxindole and a kinetic resolution of the hydroperoxicle oxindole via reduction with enolates generated from the oxindoles.
