Abstract

We have developed an efficient oxidative α-hydroxylation of β-keto esters with firstly using the structurally simple ethylenediamine-copper(ii) as a catalyst for β-keto esters activation and using visible light as the driving force for generating more active singlet oxygen (O) from triplet state oxygen (O) in the air, providing a series of α-hydroxy β-keto esters in excellent yields (up to 99%) under extremely low photosensitizer loading (0.01 mol%) and catalyst loading (1 mol%) within a short time. Moreover, the gram-scale synthesis showed the practical utility of this protocol.

摘要

我们已经开发出一种高效的β-酮酯氧化α-羟基化反应,首先使用结构简单的乙二胺-铜(II)作为β-酮酯活化的催化剂,并利用可见光作为驱动力,将空气中的三线态氧(O)转化为活性更高的单线态氧(O),在极低的光敏剂负载量(0.01 mol%)和催化剂负载量(1 mol%)下,短时间内以优异的产率(高达99%)提供了一系列α-羟基β-酮酯。此外,克级规模的合成展示了该方法的实用性。
