successfully synthesized via the Pd-catalyzed and quinazoline-directed C–H activation/acetoxylation of the corresponding 2-arylquinazolines with iodobenzene diacetate in AcOH/Ac2O. A series of acetoxylated 2-arylquinazolines have been successfully synthesized via the Pd-catalyzed and quinazoline-directed C–H activation/acetoxylation of the corresponding 2-arylquinazolines with iodobenzene diacetate in AcOH/Ac2O
抽象的 通过在相应的2-芳基喹唑啉在AcOH / Ac 2 O中用碘代苯二乙酸酯进行Pd催化和喹唑啉定向的CH活化/乙酰氧基化,已成功合成了一系列乙酰氧基化的2-芳基喹唑啉。 通过在相应的2-芳基喹唑啉在AcOH / Ac 2 O中用碘代苯二乙酸酯进行Pd催化和喹唑啉定向的CH活化/乙酰氧基化,已成功合成了一系列乙酰氧基化的2-芳基喹唑啉。
Alkyltrifluoroborates were used for Rh(III)-catalyzed ortho-alkylation of 2,4-disubstituted quinazoline via C–H bond activation. The reaction proceeded well with a broad substrate scope, providing a direct way to access high functional quinazoline core structure derivatives in yields up to 95%.
