A palladium(II)‐catalyzed direct arylation of methylene C(sp3)H bonds by 2‐methyl‐7‐aminobenzoxazole as an effective auxiliary is reported. This process exhibited high beta‐site selectivity, broad substrate scope, and compatibility with different functional groups with moderate to high yields up to 89%.
据报道,钯(II)催化了由2-甲基-7-氨基苯并恶唑作为有效助剂的亚甲基C(sp 3)H键的直接芳基化。此过程显示出高的β-位点选择性,广泛的底物范围以及与不同官能团的相容性,中度至高产率可达89%。
