A Pd0‐catalyzed four‐component cascade reaction of an aryl halide, CO, an N‐tosylhydrazone, and an amine affording α‐amino ketone has been developed. This reaction involves a sequential carbonylation, metal carbene migratory insertion, and amination. Control experiments and DFT calculations further reveal the reaction sequence and chemoselectivity of individual components in this cascade process.
已经开发了芳基卤化物,CO,N-甲苯磺酰hydr和提供α-氨基酮的胺的Pd 0催化四组分级联反应。该反应涉及顺序的羰基化,金属卡宾迁移插入和胺化。对照实验和DFT计算进一步揭示了该级联过程中各个组分的反应顺序和化学选择性。
