An attractive palladium-catalyzed three-component reaction of ortho-amino aryl diazo esters, allyl carboxylates, and carbon monoxide (CO) has been developed. This catalytic system rendered domino carbene migratory insertion and carbonylation. Remarkably, 2-indolones 3 with a C3 all-carbon quaternary center can be selectively obtained in good to excellent yields via one-pot synthesis, in which two different
已经开发了一种有吸引力的钯催化的邻氨基芳基重氮酯、羧酸烯丙酯和一氧化碳 (CO)的三组分反应。这种催化体系使多米诺卡宾迁移插入和羰基化。值得注意的是,具有 C3 全碳四元中心的 2-吲哚酮3可以通过一锅合成以良好至优异的产率选择性地获得,其中两个不同的 C-C 键和一个 C-N 键以简单的方式形成。
