利用大位阻芳基异腈作为羰基源, 发展了钯催化下的烯丙基羰基化Negishi偶联反应. 大位阻芳基异腈的使用可以有效地避免羰基化反应过程中β-H消除副反应的发生, 可专一区域选择性、高立体选择性地实现β,γ-不饱和酮的精准合成, 解决了传统一氧化碳化学中长期存在的区域选择性较差的难题. 有机锌试剂作为含碳原子亲核试剂, 反应拥有条件温和, 底物适用性广等优点.

关键词: 钯催化, 羰基化, 异腈, β,γ-不饱和酮

Herein, the palladium-catalyzed allylic carbonylative Negishi cross-coupling reaction employing sterically bulky aromatic isocyanides as the CO surrogate was disclosed. The leverage of sterically bulky aromatic isocyanide minimizes the side β-H elimination in carboxylation reaction, affords synthetically important β,γ-unsaturated ketones with high regioselectivity and stereoselectivity, thereby tackles the long-standing challenge in Pd-catalyzed allylic carbonylative cross-coupling with CO gas. Moreover, this protocol exhibits the advantage including mild reaction conditions, as well as broad substrate scope due to the utilization of Negishi reagent as the carbon nucleophiles.

Key words: palladium catalysis, carbonylation, isocyanide, β,γ-unsaturated ketones
