title: Highly efficient preparation of aryl beta-diketo acids with tert-butyl methyl oxalate.
abstract: An improved and efficient oxalylation of aryl methyl ketones was accomplished with tert-butyl methyl oxalate. This is the key step in constructing the pharmacophore of aryl beta-diketo acids, which represent a promising new class of HIV-1 integrase inhibitors. Structurally diverse aryl beta-diketo acids, including bisdiketo acids, can be prepared rapidly in impressive yields under mild conditions with this method. Advantages over conventional methods with dimethyl (or diethyl) oxalate were observed in both yield and reaction time.
