A new synthesis and application of 1-aryl-2,4-diones

Methyl ketones or ethyl acetate react with aromatic α-bromo ketones in the presence of two equivalents of tert-butoxy or diethylaminomagnesium bromide in benzene (toluene) under reflux to produce 1-aryl-2,4-diones. The conversion, apparently, occurs via aldol condensation and subsequent [1,2]- sigmatropic rearrangement of the intermediate 3-bromo-2-hydroxy ketones. A number of fused aromatic and heteroaromatic phenols have been prepared by cyclodehydration of 1-aryl-2,4-diones.
