  Cinchona衍生的相转移催化剂分批和半流式催化可见光驱动的β-二羰基化合物的对映选择性好氧氧化

  摘要：

  β-二羰基化合物的直接不对称α-羟基化反应是使用金鸡纳衍生的相转移手性光催化剂在间歇和半流过程中开发的。使用可见光作为驱动力，并使用空气作为氧化剂，可以以优异的收率（高达96％）和良好的对映选择性（高达90％ee）获得相应的产物。催化剂充当手性中心和催化中心，并与底物形成手性烯醇盐配合物，以在反应中充当光敏中心。使用半流式光化学工艺可以缩短反应时间（24 h至0.89 h），并获得良好的收率（高达93％）和对映选择性（高达ee的88％）。

  The direct asymmetric α‐hydroxylation of β‐dicarbonyl compounds has been developed using cinchona‐derived phase‐transfer chiral photocatalysts in batch and semi‐flow processes. Using visible light as the driving force and air as oxidant, the corresponding products were obtained in excellent yields (up to 96%) and good enantioselectivities (up to 90% ee). The catalyst acts as a chiral center and a catalytic

  We have developed C-6'-modified quinine quaternary ammonium salts as phase transfer catalysts for alpha-hydroxylation of beta-dicarbonyl compounds. The quinine quaternary ammonium salts, which was modified at C-6' and the N atom, had good activity for alpha-hydroxylation of B-dicarbonyl compounds. By using 5 mol % of 6-hydroxyl-N-(4'-fluoro-2'-trifluoromethyl)quinine quaternary ammonium salt as the organocatalyst, cumene hydroperoxide as the oxidant, toluene as the solvent, and 50% K2HPO4 as the aqueous alkali at room, temperature, the yield and enantioselectivity of the alpha-hydroxylation of beta-keto esters were 95% and 88%, respectively. This catalytic system was also applicable for beta-keto amides (92% yield and 76% ee). (C) 2016 Elsevier Ltd. All rights reserved.

  Abstract The asymmetric α-hydroxylation of β-dicarbonyl compounds was catalyzed by C-2′-modified cinchonine-derived phase-transfer catalysts. Excellent yields (up to 95%) and good enantioselectivities (up to 89% ee) were obtained. The reaction was carried out in a flow microreactor and similar results were obtained (up to 93% yield, 84% ee), the residence time was shortened from 24 h in batch to 2 h
