In this letter, we successfully explored a cascade Pd/Cu-catalyzed intermolecular C(sp3)–H arylation of amides and intramolecular C–N coupling reaction. This method provides a one-pot strategy to synthesize 3,4-2H-quinolinone with good regioselectivity of C–H arylation and C–N coupling from C–I and C–X bonds from readily available starting materials.
在这封信中,我们成功地探索了级联Pd / Cu催化的酰胺间C(sp 3)-H芳基化和分子内C-N偶联反应。该方法提供了一种一锅法,可从容易获得的起始原料中合成具有良好的C–H芳基化区域选择性和C–N和C–N键的C–N区域选择性的3,4-2 H-喹啉酮。
