A mild and rapid (diacetoxyiodo)benzene-mediated formal electrophilic alpha-azidation of 1,3-dicarbonyl compounds using commercially available Bu4NN3 as the azide source is reported. The reaction conditions employed are based on optimization studies conducted on the analogous halogenations with Et4NX (X = Cl, Br, 1).

We report the design and the efficient synthesis of novel spirocyclopropyl cyclohexane-1,3-dione and -1,3,5-trione units to be incorporated into potent HPPD inhibitors. New routes involving original combinations of synthetic equivalents of alpha-cyclopropyl ketone-alpha-anion and alpha-cyclopropyl ester-beta-cation are described. (C) 2010 Elsevier Ltd.
