and eco-friendly visible-light-induced protocol for the hydroacylation of quinones with α-keto acids has been developed. In the absence of any catalyst or additive, the decarboxylative hydroacylation proceeded smoothly under visible-light irradiation at room temperature. A wide range of quinones and α-keto acids were well-tolerated and afforded hydroacylation products up to 88% isolated yield. The reaction
已经开发出一种温和且环保的可见光诱导醌与 α-
酮酸的氢酰化方案。在没有任何催化剂或添加剂的情况下,脱羧加氢酰化反应在室温可见光照射下顺利进行。多种醌和 α-
酮酸具有良好的耐受性,并提供高达 88% 的分离产率的加氢酰化产物。该反应可以扩大规模,并且诱导的基团可用于进一步的合成应用。初步的机理研究表明,光敏醌吸收可见光以促进转化。
