N-heteroaromatics and γ-lactams/amides was developed. Quinoxalin-2(1H)-one, quinoline, isoquinoline, phthalazine, and benzothiazole reacted with γ-lactams/amides to give the corresponding C(sp2)–H amidoalkylation products in moderate to good yields with high regioselectivity. This visible-light-induced photocatalyst-free reaction was conducted in H2O at ambient temperature, which comply with the principles
开发了 AK 2 S 2 O 8催化的多功能 C(sp 2 )–C(sp 3 ) 键与 N-杂芳烃和 γ-内酰胺/酰胺的形成。Quinoxalin-2(1 H )-one、喹啉、异喹啉、酞嗪和苯并噻唑与 γ-内酰胺/酰胺反应,以中等至良好的收率和高区域选择性得到相应的 C(sp 2 )-H 酰胺烷基化产物。这种可见光诱导的无光催化剂反应是在环境温度下在 H 2 O 中进行的,符合“绿色化学”的原则。新的 K 2 S 2 O 8 通过对照实验研究了催化机理。
