nickel/photoredox-catalyzed enantioselective reductive cross-coupling of racemic α-chloro thioesters with aryl iodides has been developed. This strategy avoids the need for organometallic reagents or stoichiometric metal reductants. This reaction could tolerate a wide range of substrate scope with excellent reactivity and high enantioselectivities (up to 91% ee) to access a variety of chiral α-aryl thioesters
开发了第一个双镍/光氧化还原催化的外消旋 α-氯硫酯与芳基碘化物的对映选择性还原交叉偶联。该策略避免了对有机金属试剂或化学计量金属还原剂的需要。该反应可以耐受广泛的底物范围,具有优异的反应活性和高对映选择性(高达91% ee),可以得到多种手性α-芳基硫酯。证明了相应的α-芳基硫酯的合成效用。此外,我们探索了这种对映选择性自由基交叉偶联过程的机制。
