Copper-catalyzed radical methylation of 1,3-diketones with tert-butyl peroxybenzoate in air is described, providing a general pathway to α-methyl 1,3-diketones in moderate to good yields. This protocol has been scaled up to 50 g, and one of the synthesized products can be used in the synthesis of medicine, Rosuvastatin.
描述了在空气中用叔丁基过氧苯甲酸酯的铜催化的1,3-二酮的自由基甲基化,提供了以中等至良好产率获得α-甲基1,3-二酮的一般途径。该协议已放大至50 g,其中一种合成产品可用于合成药物瑞舒伐他汀。
