A metal-free BF3·OEt2 catalyzed direct decarbonylative arylation of diazoamides with readily accessible aryl aldehydes under an open-air atmosphere was developed to afford 3-aryloxindoles via 1,2-aryl migration with high selectivity. The reaction offers an efficient pathway for 3-arylation of diazoamides under relatively mild conditions, which shows a high level of functional group tolerance of both
开发了一种无金属BF 3 ·OEt 2催化重氮酰胺与易于获得的芳基醛在露天气氛下直接脱羰基芳基化反应,通过1,2-芳基迁移以高选择性得到3-芳基吲哚。该反应为重氮酰胺在相对温和的条件下进行 3-芳基化提供了一条有效的途径,显示出对给电子基团和吸电子基团都具有高水平的官能团耐受性和广泛的底物范围。3-芳环吲哚也通过未受保护的水杨醛衍生物的取代基控制的化学和位点选择性 C-H 键官能化获得。
