Copper-catalyzed methylation of 1,3-diketones with tert-butyl peroxybenzoate

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.

A Method for the C-Methylation of Cyclic β-Dicarbonyl Compounds

Cyclic β-dicarbonyl compounds (1, 4, 7, 10) were reacted with either aniline or urea in the presence of trimethoxymethane to give the enamines 2, 5, 8 and 11, resp.The latter were reduced with hydrogen over palladium-charcoal or with the dimethylamine-bor
