compounds have been carbonylated under oxidative conditions and with the catalysis of the PdI2/KI catalytic system to selectively afford previously unreported 2-(4-acylfuran-2-yl)acetamides in fair to good yields (54–81%) over 19 examples. The process takes place under relatively mild conditions and occurs via a mechanistic pathway involving Csp-H activation by oxidative monoamincarbonylation of the terminal
2-炔丙基-1,3-二羰基化合物在氧化条件下和 PdI2/KI 催化系统的催化下进行羰基化,以相当高的收率选择性地提供先前未报道的 2-(4-酰基
呋喃-2-基)乙酰胺( 54–81%)超过 19 个示例。该过程在相对温和的条件下发生,并通过涉及 Csp-H 的机械途径发生,通过底物末端三键的氧化单胺羰基化形成 2-ynamide 中间体,然后进行 5-exo-dig O-环化(通过原位形成的烯醇化物与 2-ynamide 部分的分子内共轭加成)和芳香异构化。
