Palladium-Catalyzed Regioselective C-H Bond ortho-Acetoxylation of Arylpyrimidines

[摘要]：An efficient and regioselective palladium-catalyzed ortho C-H acetoxylation reaction was developed to afford ortho monoacetoxylated arylpyrimidines in good to excellent yields by using cupric trifluoroacetate as a cocatalyst A wide variety of oxygenated arylpyrimidines were prepared with high regioselectivity and functional group tolerance yields by using cupric trifluoroacetate as a cocatalyst A wide variety of oxygenated arylpyrimidines were prepared with high regioselectivity and functional group tolerance
