A Cu(OAc)2-mediated intramolecular aromatic C–H amination proceeds with the aid of a picolinamide-type bidentate coordination group to deliver the corresponding indolines in good yields. The reaction occurs smoothly even under noble-metal-free conditions, and in some cases the use of an MnO2 terminal oxidant renders the process catalytic in Cu. The mild oxidation aptitude of Cu(OAc)2 and/or MnO2 accommodates
Cu(OAc)2介导的分子内芳族CH氨化反应通过吡啶甲酰胺型双齿配位基团进行,从而以高收率递送相应的二氢吲哚。即使在无贵金属的条件下,该反应也能顺利进行,在某些情况下,使用MnO 2末端氧化剂可使该过程在Cu中催化。Cu(OAc)2和/或MnO 2的适度氧化能力适合形成富电子的噻吩和吲哚稠合的吲哚类似物。铜基系统可以为制药和药物化学中各种潜在的二氢吲哚提供有效的方法。
