facile, economical and environmentally friendly strategy has been developed for the α-hydroxylation of β-keto esters and β-keto amides with peroxides via radical cross-coupling reaction in water under open-air conditions. This protocol allows a convenient access to various α-hydroxy-β-keto esters and α-hydroxy-β-keto amides with up to 92% yield (34 examples). Moreover, the reaction was successfully
在不使用任何过渡
金属,有机溶剂和碱的情况下,已开发出一种简便,经济和环保的策略,可在
水中在开放的条件下通过自由基交叉偶联反应将β-
酮酯和β-酮酰胺与过氧化物进行α-羟基化。空调。该方案允许以高达92%的收率方便地获得各种α-羟基-β-
酮酯和α-羟基-β-酮酰胺(34个实例)。此外,反应已成功扩大至克量,机理研究表明自由基途径参与了该羟基化反应。
