Aldehydes are a kind of important synthons and reagents in organic synthesis. The efforts on transformations of aldehydes are highly rewarding and have always attracted considerable attention. Herein, a cross-coupling of aldehydes with α-haloboronates has been achieved under dual nickel/photoredox catalysis system. Considering the α-haloboronates can be easily obtained from aldehydes with our deoxygenative
醛是有机合成中一类重要的合成子和试剂。醛类转化的研究成果丰硕,一直引起人们的广泛关注。在此,在双镍/光氧化还原催化体系下实现了醛与α-卤代硼酸酯的交叉偶联。考虑到通过我们的羰基脱氧双官能化 (DODC) 策略可以很容易地从醛中获得 α-卤代硼酸酯,该方案提供了醛与一碳延长酮产物的正式脱氧交叉偶联。温和的条件使其具有良好的官能团耐受性和广泛的底物适用性。该方法的应用是通过两种相同的醛对具有非常相似骨架的两种酮进行可调合成来实现的。
